Substrate level phosphorylation is when ADP is converted to ATP by the direct transfer of a phosphate group. The easiest type of phosphorylation to understand is that which occurs at the substrate level. Oxidative phosphorylation is the term used for the attachment of free inorganic phosphate to a molecule. o Chemiosmosis. CONTENTS 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. Hence, oxidative phosphorylation is feasible only under the aerobic conditions, and it occurs in the inner membrane of mitochondria. This is the case in human erythrocytes, which have no mitochondria, and in … ATP is the molecule that supplies energy for metabolic processes within your cells. There are different types of phosphorylation. Difference # Oxidative Phosphorylation: 1. Oxidative Phosphorylation ＆ Substrate-Level Phosphorylation. Unlike substrate level phosphorylation, it does not involve phosphorylated intermediates. This can be seen in glycolysis and Krebs cycle. Substrate-level phosphorylation inside the mitochondria occurs during the Krebs cycle, also referred to as the citric acid cycle. This occurs under both aerobic and anaerobic conditions. This is explained in the next web page on oxidative pathways. © copyright 2003-2021 Study.com. It is independent of light. (D) reduction of NADP Web. This space gets overcrowded with protons, and some of them sneak back across the membrane through an escape hatch, known as ATP synthase, which is the enzyme that helps phosphorylation of ADP to ATP. SLP will only occur if there is a reaction that releases sufficient energy to allow the direct phosphorylation of ADP. Substrate-level Phosphorylation. 2. Substrate level phosphorylation is the term used for phosphorylation that removes a phosphate from one molecule and joins it to another molecule. The addition of phosphate groups is a process referred to as phosphorylation, and in this lesson, you will learn about two types of phosphorylation that your cells use to make energy. The substrate-level phosphorylation process involves the formation of ATP upon adding a phosphate group to ADP, which takes place either inside the mitochondrial matrix during the Krebs cycle or in the cytoplasm during glycolysis. The phosphate group is donated or transfered from a phosphorylated intermediate. Try refreshing the page, or contact customer support.
