Question

Assertion : The metabolic pathway through which the electron passes from one carrier to another is called the electron transport system $(ETS)$.
Reason : $ETS$ is present in the inner mitochondrial membrane.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

Inner mitochondrial membrane contains groups of electron and proton transporting enzymes. In each group the enzymes are arranged in a specific series called electron transport chain $(ETC)$ or electron transport system $(ETS)$. An electron transport chain or system is a series of coenzymes and cytochromes that take part in the passage of electrons from one carrier to another.
