Question

why are nadh and fadh₂ necessities in the electron transport chain? (1 point) they remove electrons from the electron transport chain. they move electrons to the electron transport chain. they accept electrons in order to power the electron transport chain. they move down the electron transport chain.

Explanation:

NADH and FADH₂ are electron - carriers. In the electron transport chain, they donate electrons. Their role is to move electrons from the previous steps of cellular respiration to the electron transport chain so that the energy from these electrons can be used to generate ATP.

Answer:

They move electrons from the electron transport chain.
