Production of Alcohol by Fermentation Essay

The experiment was conducted to determine the impact different yeast amounts had on yeast fermentation. It was hypothesized that the more yeast added the more CO2 would be produced. The carbon dioxide production was measured in the fermentation of yeast with solution of no yeast in test tube 1, 1mL yeast in test tube 2, and 3mL of yeast in test tube 3 over a period of twenty minutes. All of the yeast amounts produced CO2, but test tube 3 was the most efficient of the three.

There are many processes that are needed to occur to produce something that help organisms live. Cellular respiration and fermentation are two process that are important to the survival of organisms. Cellular respiration is the way cells make ATP, which they need to survive. The process starts with the breaking down of glucose into other compounds that can be used by the cell. However, there are more steps in the process than just cellular respiration and how precise cellular respiration is depends on how much ATP can be taken from food particles in the body (Hill 646). Fermentation is mostly known in the world of beer and wine, but it also produces lactate in organisms. Fermentation is breaking glucose into separate components like water or carbon dioxide, much like that of cellular respiration. N’guessan and some peers did an experiment and they found that after fermentation had stopped, they had over 200 counts of yeast in the beer (N’guess, Brou, Casaregola, Dje 858). Under the

In this lab we tried to find what fuels yeast could metabolize and what the yields of the carbon dioxide gas that were produced from the different sugars used. We used 6 different yeast and sugar mixtures. The different yeast and sugar mixtures we used were control, glucose, sucrose, fructose, starch, and saccharin. The results for the 6 different results are presented in Tables 1-6 and Graph 1. Graph 1 is a graph of all the information in Tables 1-6. Each Table and graph is labeled approximately.

Alcohol has been the lifeblood of civilization dating thousands of years back in time, and it is clear to see the culture impact it has made throughout history. People perceive alcohol in many different ways; depending on gender, age, religious background, or social upbringing. Throughout history alcohol has affected different cultures and various demographics. It has been a source of pleasure and aesthetic in many cultures, along with being one of the oldest rites of passage, especially in modern day American society. Alcohol and drinking were also an integral part of religious observances throughout history and culture. The use of alcohol can be seen as a social lubricant, and besides being a thirst quencher, it can play a pivotal role

Alcohol is a substance that has numerous diverse affects on the body-both positive and negative. Alcohol not only kills brain cells, but when taken in profusion it has almost no constructive affects. Sure it can make one overlook his/her problems, but the consequences of drinking in excess far outweigh the benefits. It is not a crime to get drunk, however alcohol will almost always cause one to conduct them self in a way he or she would not normally behave. For instance, a sober man will not usually drive ninety-five mph down I-95, however, after consuming a good amount of alcohol, his eyesight, judgement, reflexes and abilities are hindered to the point that he feels

Alcohol is a drug that is classified as a central nervous system depressant. There are three forms of alcohol, beer, wine and distilled spirits. Alcohol is one of the most commonly used drugs in the United States and has more adverse effects that most other drugs combined. There are many aspects to consider when thinking about alcohol as a drug. There are many myths surrounding alcohol, including who uses it, what its effects are on users, social and sexual situations and the amounts people drink. The vast majority of the American population uses alcohol and in many various ways and this also causes different effects. Alcohol is also has a great causation in crimes committed by users, social, medical, and educational problems as a

The quick ratio for Boston Beer Company is 1.33. A company’s quick ratio is an indicator of a company’s short-term liquidity. This ratio is a more conservative form of the current ratio because it does not take into account inventory of the company when determining its current assets. Boston Beer Company still has a favorable ratio well above 1.0. While their current ratio is much better with all the inventory, Boston Beer Company is still a reliable company that can pay off its short term debts if need be.

Alcoholism is a prominent substance abuse issue in Western society. The treatment method of controlled drinking as opposed to abstinence is a continuing cause of controversy in alcohol research to this day. The US is different from Europe in its acceptance of controlled drinking as a goal of treatment: “in the US alcohol dependence is typically depicted as a ‘recurring disease’ and the ‘successful abstainer’ as a ‘recovering’ though never ‘recovered’ alcoholic” (Coldwell, 2005). Depending on the alcohol abuse patient’s individual characteristics, either controlled drinking or abstinence is chosen as a treatment.

The first part of the breakdown of glucose is known as Glycolysis, in which one molecule of glucose is broken down to two molecules of pyruvate (C3H4O3). The second part is the fermentation process in which the two pyruvate molecules are converted to two molecules of ethanol and two molecules of carbon dioxide.

The results from the NMR of 1-propanol showed 3 different prominent peaks with the peak at 2.2 cm-1 being the acetone. Because 1-bromopropane has three non-equivalent hydrogens it was found to represent this set of NMR data. The other product, 2-bromopropane only had 2 different types of hydrogens and would have only had 2 peaks. Further analysis of the structure of 1-bromopropane showed that the hydrogens closest the bromine group were an indication of peak A in the graph. Because of the electronegativity of the bromine, this peak was located further downfield. There were 2 neighboring hydrogens so using the n+1 rule gave the 3 peaks. Going down peak B showed the next carbon which had 5 neighboring hydrogens thus giving 6 peaks. Finally, the carbon furthest away from the bromine was found at peak C. It had 2 neighboring hydrogens and provided 3 peaks.

Alcohol is one of many dangerous substances that effects our bodies. The effects of this drug can be very harmful. Alcohol is a potent non-prescription drug sold to anyone over the national legal drinking age, 21. Unlike other deadly drugs it is easy to access. This makes it easy to over-consume and create a tragic accident, even death. It can damage a person not only physically but also mentally and emotionally. Many people each year become more and more addicted to alcohol and soon experience all of it?s dangerous effects. Even if alcohol use is discontinued, some of these damages can not be cured, because the scars have been left on those that drink and those that surround them. The only hope

Alcohol is a very serious and dangerous drug, although it is not treated this way anymore. College students have taken drinking to a new level in which, for many, is very scary. Alcohol is much more dangerous than many would think. Kids see a night of drinking as a great way to have fun and party but do not see the consequences. Getting drunk and even blacking out can lead to many problems. When alcohol is consumed in unhealthy amounts, it can lead to not only short-term effects, but long-term ones as well.

     A chemistry teacher wanted to teach his 9th grade class a lesson about the evils of liquor, so he produced an experiment that involved a glass of water, a glass of whiskey, and two worms.

Alcohol dependence (alcoholism), occurs when the body cannot function without the effect of alcohol. Alcohol affects specific neurotransmitters in the brain and when the brain becomes accustomed to the alcohols affects it can no longer function properly signals without the help of the alcohol. Once someone has developed a dependency on alcohol, they will continue to drink regardless of any serious physical complications that are caused by alcohol.
