how do electrons move in the etc
Best Answer: The answer is B. in the electron transport chain, electrons gradually loose energy, which is then used to make ATP. I think Pandra doesn't entirely understand how the electron transport chain (ETC) works. In the ETC, two electron carriers (NADH and FADH2) donate high energy electrons to protein electron acceptors called cytochrome complexes.
Electron transport chain. An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
