Question

Assertion : F₁ particles are present in the inner mitochondrial membrane.
Reason : An electron gradient formed on the inner mitochondrial membrane, forms ATP

• 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: (C)

Oxysomes or F₀ - F₁ particles are present on the inner mitochondrial membrane. The F₁ headpiece of oxysome functions as ATP-synthetase which synthesises ATP from ADP and ip (inorganic phosphate) using energy from proton gradient or ATP synthetase becomes active in ATP formation only when there is a proton gradient having high concentration of protons on F₀ side (base) as compared to F₁ side (head piece) of F₀ - F₁ particles or oxysomes.
