Biology 1002B Study Guide - Final Guide: Ethanol Fermentation, Paper Chromatography, Oxygen Evolution
Document Summary
Fermentation produces co2 as a substrate wait how could you produce co2. Fermentation is for producing enough atp to keep the cell going. but some prokaryotes, such as yeast, can use fermentation as a means of acquiring atp. Release co2 from oxidation of pyruvate lol wut lmao ur crazy. In the absence of oxygen it can readily break down glucose to produce energy using anaerobic respiration. Fermentation regenerates nad+ (from nadh) to keep glycolysis going. Smaller sugars should be utilized the quickest and sugars like sweet"n low should be utilized the slowest since it doesn"t have the digestive enzymes for it. Rate of yeast fermentation decreases in a salt solution. - the more ethanol the lower the rate of fermentation since ethanol is an alcohol and it inhibits enzymatic activity (feedback inhibition) - an increase in temperature would obviously increase the rate due to increased ke however it only does so to a certain extent (enzyme denaturation)
