Question

why is inner mitochondrial membrane impermeable to H+ ions??

Answer 1

Here's what I know:

the respiratory chain in a mitochondria uses energy derived from NADH/FADH2 to drive a proton gradient in the intermembrane space.

The inner membrane is relatively impermeable to H+ ions, so that is the electrochemical force that drives ATP-synthase

But the outer mitochondrial membrane is leaky and practically equal to cytoplasm....

I hope will clear your mind

Answer 2

Answer: Cardiolipin contribute to its relative impermeability
