Question

How many molecules of ATP are require in glycolysis to change one molecule of glucose to pyruvic acid?

• A. 1
• B. 4
• C. 2
• D. 3

Answer 1

The correct option is C 2

Glycolysis is a process in which glucose which is a six carbon compound, is converted into two molecules of pyruvate which is a three carbon compound. In the entire process of glycolysis, 4 ATP molecules are released and 2 ATP molecules are used up in the series of reactions. Hence, ATP molecules required to change one molecule of glucose to pyruvic acid are 2.

So, the correct answer is '2'.
