Pyruvic acid is acid of:
Correct answer: D. 3 carbon compound
- A. 4 carbon compound
- B. 5 carbon compound
- C. 6 carbon compound
- D. 3 carbon compound
Explanation
The correct answer is E 3-carbon compound. Pyruvic acid is a three-carbon compound. It is an important intermediate product in the process of glycolysis, which is the initial step of cellular respiration. During glycolysis, glucose, a six-carbon compound, is broken down into two molecules of pyruvic acid. Each pyruvic acid molecule contains three carbons.

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.
