Electron Transport Chain (ETC)

There are many diagrams depicting the electron transport chain (ETC). However, students should not confuse the ETC with the thyllakoid membranes in leaves of plants, which are involved in photosynthesis. Look for the right diagrams. Examples of the ETC are available on the Internet.

The second diagram is not quite correct: the pairs of electrons are pumped across the membrane at complex I (NADH dehydrogenase), III (cytochrome b-c1) and IV (cytochrome oxidase), not by CoQ itself as in the diagram.

TQ for pointing this out.
