What molecules are required by the electron transport chain?

Explanation:

there are energy-carrying molecules of NADH, FADH, and ATP that are formed in preparation for the final set of reactions, the electron transport chain.

10 NADH molecules are formed and ready to enter the electron transport chain.

c.more precipitation,but only when emission levels.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
