Question

explain electron transfer chain reaction​

Answer 1

Answer:

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.

Answer 2

Answer:

electron transfer chain is the process in which the the positive electron does not attract positive electron it attracts with negative only and on the other hand the negative electron doesn't attract itself it attracts with positive only.
