The actual net ATP yield from aerobic metabolism of one molecule of glucose is different from the theoretical yield because
A)the net production of ATP is higher than previously thought.
B)it accounts for the fact that the energy provided by NADH and FADH is required not only for ATP production but also to transport ATP across the mitochondrial membrane.
C)it eliminates the ATP derived from NADH.
D)All of these answers are correct.

The actual net ATP yield is lower than the theoretical yield because the energy provided by NADH and FADH is required not only for ATP production but also to transport ATP across the mitochondrial membrane. This is known as the proton motive force, which drives ATP synthesis but also requires energy from NADH and FADH. Therefore, option A is incorrect because the actual net production of ATP is lower than the theoretical yield. Option C is also incorrect since ATP is derived from NADH.
