Substrate level of phosphorylation

WebSubstrate-level phosphorylation is a type of chemical reaction that results in the formation of adenosine triphosphate (ATP) by the direct transfer of a phosphate group to adenosine diphosphate (ADP) from a reactive intermediate. In cells, it occurs in the cytoplasm (in glycolysis) under both aerobic and anaerobic conditions.

WebThe phosphorylation of PDHA at Ser293, localized to the PDH substrate channel, and two other well-characterized sites, Ser300 and Ser232, inactivates PDH, with the most pronounced effect imposed by the phosphorylation of Ser293 [1,2]. ... It is noteworthy that in vitro the decreased phosphorylation level activates PDH. However, ... WebWe have just discussed two pathways in glucose catabolism—glycolysis and the Krebs cycle—that generate ATP by substrate-level phosphorylation. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration.
