The number of molecules of pyruvic acid formed from one molecule of glucose at the end of glycolysis is:
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 6
Explanation
Glycolysis produces two molecules of pyruvic acid from one molecule of glucose. Each molecule of glucose undergoes a series of enzymatic reactions, resulting in the formation of two molecules of pyruvic acid.

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.
