Essays on Ethanol

Abstract

All cells in a living organism require energy to drive various cellular activities such as transport of molecules and movement among others. The rate of cellular respiration may be affected by the substrate concentration, pH level and enzyme concentration among other factors. This experiment aimed to study the rate of cellular respiration in isolated mitochondria under different conditions. It was hypothesized that if the concentration of the substrate is increased then there will be an increase in the rate of cellular respiration. Mitochondrial suspension was used as the source of succinate that was used as the substrate. The level Continue reading...

The economic argument behind using of subsidies in the economy is probably to balance the interest draw by individual players in the market to a fair ground for all. The U.S. government use subsidies to reduce on the weight of production for the producers of products. This is done through tax subsidies or the government participating in production process to prevent consumer exploitation of producers. This has been the cause of disagreement in a tough argumentative debate as to whether it is Continue reading...

Abstract. Oxidation of ethanol is carried out by the oxidizing agent, potassium dichromate. The oxidizing agent undergoes a color change followed by the completion of the reaction. This change of color is utilized to measure the absorbance of the solution.

Abstract
In today's fast moving constantly changing world every person might need some certain means for relaxation once in a while, thus, it will be very difficult to find a person who has never tasted alcohol in his life. Alcohol is one of the lightest forms of addictive substances, but still the danger of becoming addicted is huge, especially if drink alcoholic beverages on a usual basis. Of course it does not mean that our human body has any physical need for alcoholic beverages at all. This need, if appeared, is only psychological, that is why psychological programming is Continue reading...

The extreme dependence of our present day civilization on Fossil Fuels is a matter of much debate. Coal, natural gas and oil accounted for 87 percent of the world's primary energy consumption, predominantly led by the US as the largest consumer of these fuels. (Cusick, 2013) The US leads the race in the use of these fuels with other emerging nations too vying for the spot. In the US, the recent discovery of shale gas has ensured that the US will continue to dominate the global scene in the usage of conventional fossil fuels. Further, the US has also Continue reading...

Emerging Markets: Brazils quest for Comparative advantage

Why is Brazil’s agriculture so competitive? Why do its manufacturing industries lack competitiveness?
Brazil is one of the world’s leading countries in agriculture. It is a significant player in such products as beef, poultry, soybeans, sugar and coffee – in which the country is top producer, exporter or even both, according to the case. What is more, Brazil provides more than half of world-wide ethanol export.
The main reasons for such a high Brazil’s agriculture competitiveness are climate conditions: lots of sunshine, soil and water. What is more, Brazil possesses the biggest territory in the South America Continue reading...

Lab Report: Ethanol Determination Experiment

Objective: “To Determine the Ethanol content in several beverages using the enzyme alcohol dehydrogenase.”

The Chemistry behind this experiment is simple enough to understand. In the reaction carried out in the experiment, Nicotinamide Adenine Dinucleotide (NADH) is formed which can be analyzed quantitatively to find the concentration of Ethanol. The reaction involves oxidation of Ethanol to Acetaldehyde. This oxidation takes place with concomitant reduction of NAD+ to NADH. This formation of NADH can be seen in the Δ absorption at 340 nm micro level. At this wavelength, the reduced co enzyme absorbs at a very fast rate than the oxidized Continue reading...

It would be tough to choose between the positives and negatives of an electric car, because along with the number of positives it carries, it does have its share of negatives as well. However, going by the popular view that with gasoline depleting and carbon emission increasing, electric cars would be best suited for modern transport; the positives undoubtedly outnumber the negatives. As the world population grows, the need for housing and food has slowly by surely started eating into the forests, and man finds himself fighting for space with animals. As growth has to be supplemented by development, Continue reading...

There are four transitions of food production that cultures have utilized. The first is foraging where people hunt wild animals and gather plants. The second is pastoralism where people herd domesticated animals. The third is horticulture where people farm in small scales. The last is intensive agriculture where people also farm but in a larger scale (O’Neil).
Each of these types uses at least one of the three main power sources of agricultural mechanization. The first is human power. The second is animal power, and the third is mechanical power. These mechanizations, especially the machineries from the third Continue reading...

Following the story of the use of ethanol to provide warmth in cold environments, this paper presents research on the effect the consumption of ethanol has on an individual’s body temperature. Firstly, the distribution of heat in the body is done by the blood. Through the vasodilatation and vasoconstriction of blood vessels, the body loses and retains head respectively. Given that ethanol enters the bloodstream directly upon consumption, its effects are almost immediate. Its presence in the blood causes the widening of blood vessels due to its vasodilation effect (Eston & Reily, 2013).
This results in an increase in Continue reading...

Introduction

All cells carry out cellular respiration in order to meet their energy requirements and to form metabolic intermediates that can be used to form secondary products. Amongst those products formed as a consequence of cellular respiration, are ATP and CO2. The formation of ATP in the cells occurs through the use of organic molecules available in the form of food (Lehninger, Nelson, & Cox, 2008). When oxygen is not available, ATP formation goes through a fermentation process, usually, referred to as alcoholic fermentation. The process utilizes a number of different sugars as the starting material. These sugars include fructose, glucose, Continue reading...

Introduction

Esterification reactions refer to those processes between carboxylic acids and alcohols reacting together to produce esters (Smith, 2011). Ethyl ethanoate also referred to as ethyl acetate is one of the esters and is prepared through a reversible reaction between an alcohol and an acid. The process results in the production of an ester and water. The catalyst used in the reaction is sulfuric acid, which also works to remove water that is produced and thus to increase the yield of ester produced. The preparation of esters through this method is a good introduction of how equilibrium manipulation may help Continue reading...

Article Review

In this paper, I review the article Fundamentals of Beer and Hop Chemistry, authored by Keukeliere, D. (2010).
In his article, Keukeliere (2010) begins by indicating that beer, an aqueous fermented drink, is based on starch, but flavored by hops. Keukelier (2010) notes that, barley, and most specifically barley malt, is the main body of beer. In order to produce one liter of beer, a few hundred grams of barley malt are needed. However, Keukeliere (2010) indicates that in the absence of barley malt, starch-rich adjuncts such as wheat, corn or rice can be used.
Keukeliere (2010) notifies us Continue reading...

Today most of the companies follow the principles of sustainable development and pay more attention to managing reputation and image assets and risks. This trend is caused by the establishment of a new type of competition between the companies: the companies compete neither in price nor in quality tactics, they compete in ideas and principles that come with this or another product. More and more people are paying attention to ethical aspects of the company’s operation (for example, in-life testing of products). This means that ethical and corporate social responsibility principles have become one of the driving forces Continue reading...

After reading the Green Dreams article, the best biofuel is the cellulose-produced biofuel. This is primarily because the production is not dependent on food crops like other ethanol production processes that use corn, soybeans, or sugarcane. Accordingly, rather than use the kernels to produce ethanol, it is possible to use the cellulose that is found in corn plants. As such, cellulose-focused biofuel production does not compete with food crops. Accordingly, the production of ethanol using cellulose is safer because it reduces the rate of global warming considerably taking into consideration that it involves use of heat and acid then Continue reading...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects Continue reading...

Abstract

Peru is the largest producer of coca in the world. A lot of land in Peru has been dedicated to the growth of coca. Coca was a very important cash crop in Peru in the 19th century. The 20th century marked a decrease in export of coca. This was as a result of the revelation that coca was being used to make cocaine. The United States has since been the major drive force for the ban of coca. Farmers needed an alternative desperately for their product. The answer was coca wine. Coca wine is wine that has coca extractions. Continue reading...

Sugar was original derived from the French word “ Sukere” (oxford). By understand the power of sugar, as a commodity and industry, in relation with the current modern globalized market, one can better understand the impact this substance has had on both the present and in the past.
I am convinced that sugar is a powerful force that has had a great impact on history. Sugar production has not only caused the physical colonization, its use has caused us to differentiate class identity around it; today we take for granted the presence on sugar around us. Examining both the social Continue reading...

Introduction

Fermentation process refers to the conversion of sugars such as glucose to alcohol, carbon dioxide and energy in the form of ATP (Kale and Gokhale). Fermentation occurs in the absence of oxygen and converts substrates such as glucose into products such as acetate or lactic acid. During fermentation, there is no oxidation phosphorylation and thus the amount of ATP that is produced is low (Pigage, Neilsen and Greeder). One specific example of fermentation is lactic acid fermentation, which is the simplest form of fermentation. In the presence of oxygen in the cells, most organisms bypass fermentation to undergo cellular Continue reading...

Waste Management

Introduction
Dealing with waste has become an increasing concern nowadays, since it affects people’s life quality by impacting the health, it affects the aesthetics, it jeopardizes the ecosystems and in general, it negatively impacts the environmental sustainability. Domestic waste (generated by individuals) and commercial and industrial waste represent a quotidian aspect that authorities are aiming to handle, either through applying laws and guidelines for maintaining healthy and clean cities and villages, either by applying various technologies for actually managing the waste disposals. And the processes and technologies used to manage the various types of waste differ depending on Continue reading...

Abstract

Oxidation is a common problem in olive oil due to its high content of unsaturated fatty acid, this leads to nutritional losses and quality degradation, especially under microwave heating. A number of studies have been done to add natural antioxidants to reduce oxidation. This project examines the possible application of olive leaves to reduce or inhibit olive oil oxidation under microwave heating. Olive leaves were able to increase the total polyphenol content as well as reducing the peroxide value in olive oil. However, the microwave heating caused severe quality degradation (increasing peroxide value and reducing total polyphenol) especially after Continue reading...

- Yes. It will be in its flammable range to ignite since 7.8% lies within the flammable range of alcohol which is 3.3% to 19%.
- The vapor density of alcohol in air will rise since it is less dense than air.
- Since ethanol is less dense than water, it will form an upper layer on top of water and will continue to burn.( Doolittle, A. 658).
- If heat is added to the ethanol, the vapor pressure will rise since there will be an additional energy to drive the molecules.
