During cellular respiration, NADH:________.a. is converted to NAD+ by an enzyme called dehydrogenase. b. none of the choices are correct. c. is chemically converted into ATP. d. is reduced to form NAD+ delivers its electron load to the first electron carrier molecue.

Answer :

Answer:

a. is converted to NAD+ by an enzyme called dehydrogenase

Explanation:

The electron transport chain of cellular respiration is the final step that oxidized NADH and FADH2. These reducing powers are formed during glycolysis and Kreb's cycle. Complex I of the electron transport chain present in the inner mitochondria membrane is NADH dehydrogenase. This protein complex accepts electrons from NADH and oxidizes it into NAD+. NADH dehydrogenase couples oxidation of NADH with the pumping of proton towards the intermembrane space.
