WebThe pentose phosphate pathway (PPP) is an alternative way of glucose use. It consists of an aerobic and an anaerobic part. For that reason, the PPP can act as a pathway or a cycle both at the same time. Its aerobic part leads to ribulose-5-phosphate, carbon dioxide (CO2 ), and reduced nicotinamide adenine dinucleotide phosphate (NADPH). WebFructose 6-phosphate Phosphofructokinase 1 is activated by: Fructose 2,6-bisphosphate Biotin is a cofactor in the first step of gluconeogenesis.

WebJul 4, 2024 · Isomerization Phase Ribulose-5-phosphate can then be isomerized by phosphopentose isomerase to produce ribose-5-phosphate. Ribose-5-phosphate is one of the main building blocks of nucleic acids and the PPP is the primary source of production of ribose-5-phosphate. WebThis phase uses several important enzymes, including phosphopentose isomerase, phosphopentose epimerase, transketolase and transaldolase. What are the two phases of the pentose phosphate pathway? Now, we are ready to enter the first of two phases of the pentose phosphate pathway: 1) The oxidative phase and 2) The non-oxidative phase. Ribose-5-phosphate isomerase (Rpi) encoded by the RPIA gene is an enzyme (EC 5.3.1.6) that catalyzes the conversion between ribose-5-phosphate (R5P) and ribulose-5-phosphate (Ru5P). It is a member of a larger class of isomerases which catalyze the interconversion of chemical isomers (in this case structural isomers of pentose).
