Question

look at the picture, im confused that why the H+ ion enter the ATP synthase so that it can form ATP

Answer 1

it actually creates an electrochemical gradient across the membrane which drives the rotation of the f1 subunit....rotation of f1 subunit through 120deg creates 1 ATP

Answer 2

where is the energy come from? the energy forms ATP

Answer 3

wait...i know it...but i cant explain it 2 u..let me find d exact words....give me a min....

rather than me explaining..u watch dis...u will understand best..:D

Answer 5

Essentially what is happening is the the electron transport chain pumps H+ into the inter mitochondrial membrane as the electrons travel along it, creating a proton gradient.

ATP synthase allows the Protons a way to travel into the inner mitochondrial membrane space which causes basically causes ATP synthase to spin (which is really pretty awesome) allowing it to catalyze the formation of ATP from a phosphate and ADP

Answer 6

Think of kind of like a hydroelectric damn, it is a great analogy

Answer 8

Cool.
