Jacquelyn Buchanan · Answer 1

C. NADH drop electrons off to the electron transport chain to become NAH+. This NAD + is then required by the Kreb's Cycle to strip electrons off the carbon chain in the various steps of the Kreb's Cycle.

Ronald Pierce · Answer 2

The correct option is option C.

Which is an NAD + molecule.

Explanation: Krebs cycle and electron transport chain are important steps in cellular respiration. In the Krebs cycle, there is a need of NAD + molecule which is then in Krebs cycle reduced to form a NADH2 molecule. NADH2 is also an energy currency. It is then oxidized in the electron transport chain, giving electron in electron transport chain and return to Krebs cycle as NAD+. Now in the Krebs cycle, it is ready to take electrons again.
