Substrate level phosphorylation and oxidative phosphorylation are two types of phosphorylation processes that occur inside living organisms. Oxidative Phosphorylation: Oxidative phosphorylation refers to a type of phosphorylation which uses the energy released from the electron transport chain to generate ATP. High energy molecules such as NADH and FADH2 that are formed in the glycolysis, Krebs cycle, and fatty acid cycle, are oxidized back in the electron transport chain. The key difference between substrate level phosphorylation and oxidative phosphorylation is that in substrate level phosphorylation, a phosphate group from a phosphorylated compound is directly transferred to ADP or GDP to form ATP or GTP without involving another molecules while in oxidative phosphorylation, nutrients or chemicals provide the energy to transfer a phosphate group to ADP and produce high energy ATP with the help of electron or H+ transport system. It can also add a phosphate group to guanosine diphosphate (GDP) in order to form a guanosine triphosphate (GTP). It occurs during terminal oxidation of reduced coenzymes generated in … 1. 2 ATP from substrate-level phosphorylation 6 NADH yields 18 ATP (assuming 3 ATP per NADH) by oxidative phosphorylation 2 FADH 2 yields 4 ATP (assuming 2 ATP per FADH 2 ) by oxidative phosphorylation Oxidative phosphorylation is an indirect method of phosphorylation in which the energy liberated in the electron transport chain is used in generating ATP. The energy released during the breakage of the phosphate group is used to phosphorylation of ADP in substrate level phosphorylation, and it is known as reaction coupling. Oxidative phosphorylation uses an electrochemical or chemiosmotic gradient of protons (H+) across the inner mitochondrial membrane to generate ATP from ADP, which is a key difference from substrate-level phosphorylation. During oxidative phosphorylation NADH is oxidized to NAD+, yielding 2.5 ATPs, and FADH2 yields 1.5 ATPs when it is oxidized. This is distinct from oxidative phosphorylation that occurs in the mitochondria. The energy released by those molecules are used in the generation of ATP in the oxidative phosphorylation.
