they produce ATP from ADP and inorganic phosphate. The number of ATP molecules
synthesized depends upon electron donor.
Oxidation of one molecule of NADH gives rise to 3 molecules of ATP, while oxidation
of one molecule of produce two molecules of ATP.

phosphorylation.
The energy released during ETC is used to make ATP with the help of ATP synthase,
which consists of two major parts F1 and F0.
F1 is a peripheral membrane protein complex having site for synthesis of ATP from
ADP and inorganic phosphate. F0 is integral membrane protein that form channel for
proton.
For each ATP produced 2H+ passes through F0 from the intermembrane space to the
matrix down the electrochemical proton gradient.
