Question
The mechanism of ATP formation both in chloroplast and mitochondria is explained by ______.
Options:
A .  Relay pump theory of Godlewski
B .  Munch’s pressure/mass flow model
C .  Chemiosmotic theory of Mitchell
D .  Cholondy – Went’s model
Answer: Option C
:
C
As per Peter Mitchell’s chemiosmotic – coupling hypothesis, outward pumping of protons across the inner chloroplast or mitochondrial membrane results in accumulation of protons between outer and inner membrane. A proton gradient is thus established. As protons now flow back passively down the gradient, the proton motive force is utilized to synthesize ATP.
