Question

Complex I transfers electrons to Q (coenzyme Q) in one of the reactions in the electron transport chain. Which molecule is reduced and which is oxidized in this reaction?

Complex I is reduced because it loses electrons and Q is oxidized because it gains electrons

Complex I is oxidized because it loses electrons and Q is reduced because it gains electrons

Complex I is reduced because it gains electrons and Q is oxidized because it loses electrons.

Complex I and Q are both oxidized because electrons are moved from one molecule to the other.

Explanation / Answer

The correct option is option 2.

Complex I is oxidized because it loses electrons and Q is reduced because it gains electrons.

Complex 1 is also called NADH-Coenzyme Q reductase as this complex tranfers electrons from NADH to coenzyme Q. Therefore, the complex is said to be oxidized and the coenzyme Q is reduced.
