Detailed explanation-1: -These molecules are capable of further producing ATP molecules by transfer of electrons and with the enzyme ATP synthase. One NADH molecule produces 3 ATP molecules. Whereas one FADH2 molecule produces 2 ATP molecules.
Detailed explanation-2: -FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain.
Detailed explanation-3: -The oxidation of one molecule of NADH thus leads to the synthesis of three molecules of ATP, whereas the oxidation of FADH2, which enters the electron transport chain at complex II, yields only two ATP molecules.
Detailed explanation-4: -Assertion (A): Oxidation of one molecule of FADH2 produces two molecules of ATP, while that of one molecule of NADH gives rise to three molecules of ATP. Reason (R): The number of ATP molecules synthesised depends on the nature of the electron donor.
Detailed explanation-5: -Assertion :Oxidation of one molecule of NADH gives rise to 3 molecules of ATP and that of one molecule of FADH2 produces 2 molecules of ATP. Reason: The number of ATP molecules synthesised depends on the nature of the electron donor.
