What is the net ATP yield for a muscle cell that stores one dietary glucose molecule as glycogen and then releases it and sends it through glycolysis?
A)0
B)1
C)2
D)3
E)4

Question

Quizplus · Accepted Answer

One glucose molecule yields 2 ATP through glycolysis. However, since the glucose was stored as glycogen, it requires one ATP to activate glycogen phosphorylase to release the glucose from glycogen. Therefore, the net ATP yield is 2 ATP - 1 ATP = 1 ATP.
