respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best sugar to use in the fermentation process.

forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide and ethanol. They are

- Always starts anaerobic in the cytosol – glycolysis – only 2 ATP saved - By the end of the process‚ you get 2 pyruvate – 3-carbon molecules NO O2 - Fermentation 1. Lactic Acid – your muscles ache because of the accumulation of lactic acid. 2. Alcohol Fermentation- ethanol is fancy word for alcohol. Alcohol fermentation is alcohol + CO2 O2 Aerobic * Respiration * Mitochondria * Matrix – Krebs Cycle – C6 – gives you 2 more ATP * Innermembrane- ETS – 34 ATP Mitochondria

Abstract Research will be done and two experiments will be conducted to evaluate ethanol as a fuel‚ the experiments are Fermentation and Calorimetry. Fermentation will find the best combination of sugar and yeast for optimum ethanol production and the Calorimetry experiments test ethanol against other alcohols and fuels to see how it matches up in terms of energy production. Fermentation shows glucose and baker’s yeast as the fastest producers of ethanol and the calorimetry proves that ethanol and

carboxyl group is replaced by a hydrocarbon group. This hydrocarbon group is provided by an alcohol‚ most commonly ethanol‚ or grain alcohol. An alcohol is a chemical compound whose molecular structure is comprised of a hydroxyl group –OH chemically bonded to a carbon. One of the simplest and most common esters is ethyl ethanoate‚ or ethyl acetate‚ a combination of ethanoic acid and ethanol. The ethyl ethanoate chemical reaction is C2H4O2 + CH3CH2OH C4H8O2 + H2O. As seen in this reaction‚ an acid and

USA over a Barrel The cost of a barrel of oil this summer reached a record high of nearly $100. How has this happened and how much higher could oil go? The United States dependence on foreign oil is at an all time high. Nations supplying this oil are pumping at a record pace and maximum capacity. If any of these nations fail to supply the U.S. because of a terror attack or bad relations‚ the economy would be negatively impacted. How can the U.S. reduce dependence on imported fuels and diversify

Introduction Ethanol most commonly which is produced through the fermentation of glucose by yeast cells. Fermentation is an energy-yielding process that cells carry out in the absence of oxygen. Although fermentation does not provide much usable energy for the cell‚ it is sufficient for yeast cells. Yeast cells produce ethanol and CO 2 as byproducts‚ and the ethanol produced valuable energy source. There is much interest in ethanol as an energy alternative which are nonrenewable and contribute significantly

Caleb Campbell Larger Amounts of Sugar Result In Greater Fermentation Rates Introduction: This experiment was conducted to find out if using larger amounts of sugar in a water-yeast solution would cause higher rates of fermentation. Fermentation is an anaerobic (without oxygen) cellular process in which organic foods are converted into simpler compounds‚ and chemical energy (ATP) is produced (Biology-Online.org‚ 2008). Fermentation is a natural occurring process that humans have used and controlled
