Question

How does proton flow cause rotation of F0? How many H+ are required for each turn of the vertebrate F0?

Answer 1

Answer=

Proton flow causes rotation of Fo

ATP synthesis carried out by ATP synthase it is F₀F₁ complex.which catalyses ATP synthesis as proton s flow back through the inner mmb. down electrochemical proton gradient.

It contains 2 components F_{0 &} F₁ components

The binding change mechanism is widely accepted model of ATP synthesis

Atp synthesis is coupled with conformational change in ATP synthase generated by rotation of $\gamma$ subunit.

Proton translocation occurs through the F₀ powers the rotation of $\gamma$ subunit of F1 ATPase

leading to a changes in the conformation of the nucleotide binding sites in F₁ $\beta$ subunit

By means of binding change mechanism ,the F₀F₁ complex harneses the proton motive force.to power ATP synthesis

The proton required to drive the synthesis of one ATP molecule is FOUR
