Blair · Answer 1

The correct answer is c. consume two ATP molecule

Explanation:

Glycolysis is the process in which glucose is partially breakdown into two pyruvate molecules. Glycolysis is divided into two-phase the first phase is the preparatory phase and the second phase is the payoff phase.

In preparatory phase energy is consumed and the formation of two molecules of glyceraldehyde 3 phosphate (triose phosphate) takes place with the consumption of two ATP, therefore, this phase is called energy investment phase.

These two ATP are consumed when fructose 6 phosphate converts into fructose 1,6 bis-phosphate. Therefore, the right answer is c.
