Question

when a molecule of pyruvic acid is subjected to anaerobic oxidation, there is 1. Loss of 2.5 molecules of atp 2. Loss of 5 molecules of atp 3. Gain of 2 molecules of atp 4. Gain of 1.5 molecules of atp

Answer 1

$\huge{\boxed{\mathbb{\red{ANSWER}}}}$

When a molecule of pyruvic acid is subjected to anaerobic oxidation, there is loss of 3 ATP.

Explanation:

The pyruvate is formed during the glycolysis of the glucose. In the absence of oxygen, the pyruvate is subjected to the anaerobic oxidation to produce the lactic acid with the utilization of 3 ATP and regeneration of the 2 NADH that will be used again in the process of glycolysis.

Hence, the correct answer is "Loss of 3 ATP molecules".
