Question

How many ATP are produced in electron transport chain?

Answer 1

Electron transport chain:

1. The oxidative phosphorylation process, also known as the electron transport chain, is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP.
2. Both photosynthesis and cellular respiration take place in mitochondria.
3. By transferring electrons from NADH and FADH₂ through a series of complexes and electron carriers, these carriers ultimately produce ATP.
4. The electron transport cycle generates around 30–32 ATP molecules, according to a recent study.
5. This NADH consequently produces one to two ATP.
6. The highest yield of ATP produced per glucose in eukaryotic cells is potentially between 36 and 38 depending on how the two NADH made in the cytoplasm during glycolysis reach the mitochondria and if the resulting yield is 2 or 3 ATP per NADH.
7. The oxidative phosphorylation process, which produces ATP as a result of an electrochemical gradient created by the electron transport chain, is a collection of four protein complexes that link redox processes.
8. Both photosynthesis and cellular respiration take place in mitochondria.
