The electron process makes water and ATP and is sometimes called Oxidative phosphorylation because it require oxygen.
Step-by-step explanation
Oxidative phosphorylation is a process that take place in the mitochondria during aerobic respiration.
This process result to formation of ATP as a result of transfer of electrons from NADH or FADH2 to O2.
The electron transport chain and ATP synthesis are mainly embedded in the inner mitochondrial membrane.
