Which of the following statements about the electron transport chain is NOT correct A It is located in the inner mitochondrion membrane B Cytochrome c accepts electrons from complex I C Cytochrome oxidase (complex IV) accepts electrons from Cytochrome c D Coenzyme Q accepts electrons from complex I and complex II

The correct answer is:

B. Cytochrome c accepts electrons from complex I

Explanation:

• Statement A (Correct): The electron transport chain (ETC) is located in the inner mitochondrial membrane.
• Statement B (Incorrect): Cytochrome c does not accept electrons from Complex I. Instead, it accepts electrons from Complex III and transfers them to Complex IV.
• Statement C (Correct): Cytochrome oxidase (Complex IV) accepts electrons from cytochrome c and passes them to oxygen, the final electron acceptor.
• Statement D (Correct): Coenzyme Q (ubiquinone) accepts electrons from both Complex I and Complex II and transfers them to Complex III.
