Question

what are the functions of the high - energy electrons in the electron transport chain? (1 point)
they make atp from adp.
they create atp synthase.
they hold water bonds.
they carry nadh and fadh₂.

Explanation:

In the electron - transport chain, high - energy electrons are used to pump protons across a membrane, creating a proton gradient. This gradient is then used by ATP synthase to make ATP from ADP. ATP synthase is an enzyme and not created by high - energy electrons. High - energy electrons do not hold water bonds. NADH and FADH₂ carry the high - energy electrons, not the other way around.

Answer:

They make ATP from ADP.
