select the correct answer

Apologies for the confusion. The correct answer is:

6 NADH, 2 ATP, 4 CO2, and 2 FADH2

Why are NADH and FADH2 necessities in the electron transport chain?

They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.

They move electrons to the electron transport chain.
They move electrons to the electron transport chain.

They move down the electron transport chain.
They move down the electron transport chain.

They accept electrons in order to power the electron transport chain.
