Assertion: The inner membrane of mitochondria contains systems involving electron transport.
Reason: The mitochondrial matrix contains enzymes of Kreb's cycle.

Options

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

Answer

B

Explanation

The metabolic pathway through which the electron passes from one carrier to another is called the electron transport system. This process occurs in the inner mitochondrial membrane.
Kreb cycle serves as a common oxidative pathway for carbohydrates, fats, and proteins it requires the presence of oxygen and is confined to the mitochondrial matrix.
