Where does oxidative phosphorylation take place in glycolysis?

If you’ve ever seen a metabolic pathway diagram, you’re likely familiar with the concept of redox reactions. Most of the metabolic reactions in a cell are redox reactions, which consists of a chemical reaction that produces or consumes a reducing agent or an oxidizing agent. In oxidative phosphorylation the transfer of electrons is a redox reaction, and it happens through a series of reactions that are called the electron transport chain (ETC). A key component of the ETC

Where does oxidative phosphorylation take place in catabolic glycolysis?

The first reaction in catabolic glycolysis is the breakdown of glucose to form two pyruvates. These two pyruvates can then be used to either enter the tricarboxylic acid (TCA) cycle or oxidative phosphorylation. If the two pyruvates are used to enter the TCA cycle, the last step is the breakdown of the second carbon atom from each of the two pyruvates. As you can see, oxidative phosphory

Finally, oxidative phosphorylation occurs in the final step of glycolysis—the conversion of pyruvate to acetyl-CoA in the cytoplasm. This reaction is responsible for generating the energy-carrying molecule adenosine triphosphate (ATP) in a reaction known as oxidative phosphorylation. While the overall process of oxidative phosphorylation takes place in the inner mitochondrial membrane, the first two steps occur in the cytosol.

Where is oxidative phosphorylation in glycolysis?

The answer to this question depends on which pathway of glycolysis oxidative phosphorylation takes place in the first place. If oxidative phosphorylation in glycolysis occurs through the Embden-Meyerhoff-Parnas pathway, then the enzymes of oxidative phosphorylation are embedded in the mitochondrial matrix or the cristae. In this case, the pyruvate is produced on the enzymes of the mitochondrial matrix, and the NADH and the FADH2

Where does oxidative phosphorylation take place in anaerobic glycolysis?

Under anaerobic conditions, the energy produced by glycolysis is stored as ATP in the form of ADP. Since the reaction is not reversible, the metabolic pathways that do not generate ADP are optimal for this purpose. Thus, oxidative phosphorylation is not part of anaerobic glycolysis.
