Glycolysis initiates glucose to break down into 2 pyruvate ions. 4. The amount of sugar will greatly affect the yeast fermentation process because with less sucrose there will be a short supply of glucose molecules for the yeast to ferment with and as a result pH levels will not drop as much due to less CO2 being production. 0000003136 00000 n
