Answer 4

I think its D. The first five steps of glycolysis use ATP to “activate” glucose, redistributing energy in the molecule and splitting it in half. The rest of the pathway then stores some energy in two molecules of the electron carrier, NADH. Other steps extract more of the energy, regaining the two ATP molecules invested earlier plus producing two more. The net gain is therefore two NADHs and two ATPs per molecule of glucose.

Answer 5

It was C. :/ But, Thanks! :)
