What is the number of carbon atoms in pyruvic acid?
Correct answer: C. 3
- A. 8
- B. 2
- C. 3
- D. 4
Explanation
Pyruvic acid has the molecular formula C3H4O3. It has 3 carbon atoms.you can remember it by keeping in mind the fact that one glucose molecule splits into two pyruvic acid molecules in glycolysis. As glucose has 6 C-atoms, each pyruvate should have 3 C-atoms.

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.
