Which mitochondrial complex donates electrons to molecular oxygen during ETS?
- A Complex I
- B Complex II
- C Complex III
- D Complex IV
Answer & Solution
Correct Answer
(D) Complex IV
Step-by-step Solution
Detailed explanation
Complex IV, also known as cytochrome c oxidase, is the mitochondrial complex that donates electrons to molecular oxygen during the Electron Transport Chain (ETC). It is the final complex in the ETC and plays a crucial role in transferring electrons to oxygen to form water.
