Electrons move spontaneously through the mitochondrial ETC from carriers with lower redox potential to higher ones. Which component has the highest redox potential?
Q1. Electrons move spontaneously through the mitochondrial ETC from carriers with lower redox potential to higher ones. Which component has the highest redox potential?
Answer: Oxygen
Explanation: Oxygen has the highest redox potential, acting as the final electron acceptor. Cytochrome a3 is tempting but it precedes oxygen in the chain.
