Question

What is the role of ATP synthase?

Answer 1

ATP synthase is a membrane protein which converts the proton gradient across membrane into energy storing molecule ATP, important for biological purposes.

Explanation:

I have explained what ATP synthase is now waht is the structure of ATP synthase is as follows

![users.rcn.com/

there is a rotor trans-membrane part in the protein `F_0` which is attached to `F_1` through a shaft/stalk. there is an anchor protein which connects `F_1` to membrane.

working of ATP synthase

where the rotor mechanism also called `F_0` is the one which allows proton to pass across the membrane. As proton goes in `F_0`, `F_0` rotates holding proton in the pockets assigned to proton.

now as the `F_0` moves the shafts/stalk also moves which help the `F_1` to convert the ADP and Phosphate group to combine and convert into ATP.

the link below is a good one which describes what ATP synthase does and its structure.
