Why does glucose oxidation occur in a series of steps?
A)One step wouldn't allow the energy released to be harnessed efficiently.
B)It doesn't have to; it just happens to be that way.
C)Glycolysis evolved first and steps were just added over time.
D)Glucose cannot pass into the mitochondria and oxygen cannot enter the cytosol.
E)Glucose is reduced, not oxidized.

Question

Quizplus · Accepted Answer

Glucose oxidation occurs in a series of steps because if it occurred in just one step, the energy released would not be harnessed efficiently. Breaking down glucose into smaller steps allows the cell to capture more of the released energy in the form of ATP.
