Pentose phosphate pathway reaction

Web5. mar 2024 · It includes two reactions generating NADPH. In the first of these, oxidation of glucose-6-phosphate (catalyzed by glucose-6-phosphate dehydrogenase), produces NADPH and 6-phosphogluconolactone. 6-phosphogluconolactone spontaneously gains water and loses a proton to become 6-phosphogluconate. WebThe pentose phosphate pathway occurs in the cytosol and accounts for the complete oxidation of glucose, producing NADPH and CO2 but not ATP. The sequence of reactions of the pathway occurs in two phases: an oxidative nonreversible phase and a nonoxidative reversible phase.

WebThe oxidative pentose phosphate pathway is a major source of reducing power and metabolic intermediates for biosynthetic processes. Some, if not all, of the enzymes of the pathway are found in both the cytosol and plastids, although the precise distribution of their activities varies. WebThe pentose phosphate pathway (PPP — also known as the hexose monosphosphate shunt) is a cytosolic pathway that interfaces with glycolysis. In this pathway, no ATP is directly produced from the oxidation of glucose 6-phosphate; instead the oxidative portion of the PPP is coupled to the production of NADPH.
