WebPentose phosphate pathway. The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt and the HMP Shunt) is a metabolic pathway parallel to glycolysis. [1] It … 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. citizenship lawyer fees
