They make ATP from ADP.

Answer 2

[AI-generated answer — Explain Bot]

The correct answer is: They carry NADH and FADH.

Explanation: The high-energy electrons in the electron transport chain serve an important role in the process of oxidative phosphorylation, which is the final step in cellular respiration. These electrons are transferred from NADH and FADH2 (which are produced earlier in the respiration process) to protein complexes in the electron transport chain.

As these electrons move from one protein complex to another, they release energy which is used to actively pump protons (H+) across the inner mitochondrial membrane. This creates an electrochemical gradient, with more protons on one side of the membrane than the other. This gradient is then used to power ATP synthase, an enzyme that generates ATP from ADP and inorganic phosphate.

So, while high-energy electrons do not directly create ATP synthase or hold water bonds, they play a crucial role in the production of ATP from ADP by carrying NADH and FADH2 molecules and facilitating the transfer of electrons throughout the electron transport chain.
