In the second half of the glycolytic pathway, ____ ATP molecules are produced and with the offset of ____ ATPs consumed in the first half, the net yield is ____ ATPs per glucose.

Question

Quizplus · Accepted Answer

In the second half of glycolysis, four ATP molecules are produced through substrate-level phosphorylation. However, two ATPs were initially used in the energy requiring reactions of the first half, resulting in a net gain of two ATPs per glucose molecule. Therefore, the correct option is B which reports a yield of four ATPs produced in the second half, two ATPs consumed in the first half, and a net gain of two ATPs per glucose.

In the Second Half of the Glycolytic Pathway, ____ ATP
