(b) more than 30

(c) more than 50

(d) more than 100

This question was addressed to me in an internship interview.

I want to ask this question from Aerobic Respiration topic in chapter Nucleus & Aerobic Respiration of Cell Biology

Answer 1

Right option is (b) more than 30

For explanation: The end products of glycolysis, pyruvate and NADH can be metabolized in the mitochondria in presence of oxygen. This process can generate more than 30 additional molecules of ATP.
