Question

F particles are present in the inner mitochondrial membrane. 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)

If assertion is true but reason is false

Answer 2

Oxysomes or F - F particles are present on the inner mitochondrial membrane. The F 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 F side (base) as compared to F side (head piece) of F - F particles or oxysomes.
