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.

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.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
