Question

how many electrons must move down the electron transport chain before energy is made? (1 point)
4
3
2
5

Explanation:

In the electron - transport chain, energy production is associated with the transfer of electrons. Two electrons moving down the electron - transport chain initiate the processes that lead to energy production, such as the pumping of protons across a membrane to create a proton - motive force which is used to generate ATP.
