In the context of mitochondrial structure, where does the electron transport chain occur?
- A.Outer mitochondrial membrane
- B.Mitochondrial matrix
- C.Intermembrane space
- D.Inner mitochondrial membrane
Show correct answer & step-by-step solution
Correct answer: D — Inner mitochondrial membrane
Solution
- The inner mitochondrial membrane contains the protein complexes of the electron transport chain.
- These complexes facilitate the transfer of electrons and the pumping of protons.
- The matrix is the site of the Krebs cycle, not the electron transport chain.
- Hence the answer is (D).
