Question

The number of ATP molecules utilised for the breakdown of one molecule of glucose during glycolysis is

• A. 62
• B. 2
• C. 8
• D. 4

Answer 1

The correct option is B 2

Glycolysis is the process in which there is partial oxidation of the glucose molecule carried out. The glucose molecule is broken down to give two molecules of pyruvate. There are 4 ATPs produced but 2 are used up, so the net yield of glycolysis is 2 ATP.

Thus, the correct answer is option B.
