Question
In the electron transport chain, in terminal oxidation, the cytochrome, which donates electrons to O2 is
cytochrome- b
cytochrome- c
cytochrome- a3
cytochrome- a
Solution
C.
cytochrome- a3
The cytochrome- a3 is an electron carrier which contains copper with iron. It picks up electrons and through copper, it hands over electrons to oxygen. Oxygen accepts electrons finally.
