Question

Examine the molecular model of the partial structure of the yeast atp synthase. which part of the molecule spans the inner mitochondrial membrane?

Answer 1

ATP synthase or Complex V spans the inner mitochondrial membrane. ATP synthase and respiratory chain are biochemically SEPARATE systems and they are linked only by PROTON MOTIVE FORCE. Proton motive force is generated by electron transport.

ATP synthase resembles a ball on a stick which locates in the inner mitochondrial membrane. The answer is FO rotor.
