Fig. Lactobacillus spec. Examples of substrate-level phosphorylation are the removal of inorganic phosphates from 1,3-biphosphoglycerate or phosphoenolpyruvate to form 3-phosphoglycerate or pyruvate, respectively, as well as ATP. Substrate-level phosphorylation occurs in the cytoplasm of cells as part of glycolysis and in mitochondria as part of the Krebs Cycle under both aerobic and anaerobic conditions. Substrate-level phosphorylation is less complicated but also not as universal as oxidative phosphorylation. Citric Acid Cycle also has substrate phosphorylation when GDP+Pi forms GTP, which by simple conversion forms ATP. As electrons flow down the chain, the protein complex undergoes reduction-oxidation reactions. Phosphorylase s and kinase s catalyse this process. substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Both phosphorylation and dephosphorylation are carried out by enzymes (e.g., kinases, phosphotransferases). NADH and FADH release their electrons down the electron transport chain and is accepted by protein complexes. Figure \(\PageIndex{1}\): Adenine nucleotides. All rights reserved.
