How many ATP are produced when one molecule of FADH2 is oxidised to FAD through electron transport system?
2
3
1
4
A.
2
During the course of electron transfer, when electrons passes from one carrier molecule to another in the ETC. They get coupled to ATP synthase for the production of ATP from ADP and Pi (inorganic phosphate). The number of ATP molecule synthesised depends upon the nature of the electron donor. One molecule of FADH2 on oxidation provides or produces 2 molecules of ATP because its redox potential is higher than NADH and thus, enters the ETS after by passing the first site of phosphorylation.
