Which of the following statements best summarizes ATP use and production in the catabolism of each glucose molecule in glycolysis?
A) two molecules of ATP are used, and two molecules of ATP are produced
B) two molecules of ATP are used, and four molecules of ATP are produced
C) four molecules of ATP are used, and two molecules of ATP are produced
D) four molecules of ATP are used, and four molecules of ATP are produced

Question

Quizplus · Accepted Answer

In the glycolysis pathway, two molecules of ATP are used in the early steps to phosphorylate glucose and its intermediates. Later, four molecules of ATP are produced, resulting in a net gain of two ATP molecules per glucose molecule catabolized.
