Which of the molecules listed below is a product of the fermentation of glucose by yeast?
Correct answer: B. C2H5OH
- A. (C6HI0O5)n
- B. C2H5OH
- C. C6H12O6
- D. CH3OH
Explanation
This is ethanol, which is the primary product of the fermentation of glucose by yeast. During fermentation, yeast cells break down glucose into ethanol and carbon dioxide through a process called alcoholic fermentation.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
