The Kreb's cycle produces the most NADH during cellular respiration, generating a total of 6 NADH molecules per glucose molecule processed. In comparison, glycolysis only produces 2 NADH, while the electron transport chain does not produce any. Therefore, the process that yields the highest NADH is the Kreb's cycle. ;
The Kreb's cycle produces the most NADH during cellular respiration, generating a total of 6 NADH molecules per glucose molecule. In comparison, glycolysis only produces 2 NADH, while the electron transport chain does not produce any. Therefore, the correct answer is D, Kreb's Cycle.
