Question

Number of oxygen molecules required during glycolysis of one glucose molecule is

• A. 38
• B. 36
• C. 2
• D. Zero

Answer 1

The correct option is D Zero

Glycolysis of one glucose molecule produces two molecules of pyruvic acid as the end product. However, during each oxidative step, no molecular oxygen is required as such. Oxidation occurs by removal of hydrogen and not addition of oxygen.

So the answer is 'Zero'.
