Question

Metabolic fate of pyruvic acid depend on

• A. Cellular energy
• B. Availability of oxygen
• C. Type of respiration
• D. All of the above

Answer 1

The correct option is D All of the above

Pyruvic acid is formed by partial oxidation of glucose by the process of glycolysis.

A. The fate depends upon the cellular needs. There are three major ways by which pyruvic acid is handled by different cells, that are lactic acid fermentation, alcoholic fermentation and aerobic respiration.

B. In the availability of oxygen aerobic respiration takes places.

C. In the absence of oxygen alcoholic fermentation and lactic acid fermentation takes place and in presence of oxygen aerobic respiration takes place.

D. Therefore, all are correct.

So, the correct answer is 'All of the above'.
