YEAST FERMENTATION LAB
2025 - 2026 with 100%
correct answers (passed)
In plants and yeasts (fungi), the process of fermentation produces -
answer ethanol (alcohol) and carbon dioxide
alcoholic fermentation is - answer anaerobic process in which cells
convert pyruvic acid into carbon dioxide and ethyl alcohol; carried out by
many bacteria and fungi such as yeasts
alcoholic fermentation equation - answer pyruvic acid + NADH --> alcohol
+ CO2 + NAD+
Why is cellular respiration different from fermentation? - answer Cellular
respiration requires oxygen to release energy from food. Fermentation, on
the other hand, doesn't require oxygen and uses less energy to break
down sugars.
Why does fermentation occur? - answer 1. To free up the electron carriers
so they can keep Glycolysis going and make ATP
2. So ATP can still be produced in the absence of oxygen.
Where does fermentation occur in the cell? - answer cytoplasm
When oxygen levels are low in bacteria and animal cells, the products of
glycolysis undergo fermentation in the cytoplasm to produce what? -
answer Lactic Acid
