Question
Which one of the following components of the electron transport chain only accepts electrons, and does not donate them?
Solution
The component of the electron transport chain that only accepts electrons and does not donate them is Cytochrome c oxidase (Complex IV). This enzyme complex accepts electrons from cytochrome c, facilitates their transfer to oxygen (the final electron acceptor), and does not donate them further.
