phosphohexose isomerase - Medical Dictionary

WebThe pentose phosphate pathway can use any available molecules of glucose-6-phosphate, whether they are produced by glycolysis or other methods. Now, we are ready to enter the first of two phases of the pentose phosphate pathway: 1) The oxidative phase and 2) The … Webphosphopentose isomerase. Under many metabolic conditions the phosphogluconate pathway ends at this point. The net result is the production of NADPH for reductive synthesis and the production of D-ribose-5-phosphate for nucleotide synthesis. However, many cells need more NADPH than ribose-5-phosphate or they may not need ribose-5-phosphate at all. greeting card printable free

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).
