NEET · BiologyMedium
In the electron transport system of mitochondria, which complex is responsible for the transfer of electrons from cytochrome c to oxygen?
- A.Complex I
- B.Complex II
- C.Complex III
- D.Complex IV
Show correct answer & step-by-step solution
Correct answer: D — Complex IV
Solution
- Complex I and II donate electrons to ubiquinone.
- Complex III transfers electrons from ubiquinol to cytochrome c.
- Complex IV contains cytochromes and and two copper centers.
- Complex IV transfers electrons from cytochrome c to to form .
- Hence the answer is (D).
