The Electron Transport Chain and Pentose Phosphate Pathway biochemistry The pentose phosphate pathway (PPP) in neuronal energy metabolism. Download Scientific Diagram biochemistry Why is the Pentose Phosphate Pathway so active in erythrocytes? Biology Stack Exchange Glucose metabolism begins with its transport into cells via GLUT transporters, where it is phosphorylated to glucose 6 phosphate (Glucose 6 P). This molecule can enter various pathways, including the pentose phosphate pathway or hexosamine biosynthesis. untitled1.html The return of metabolism: biochemistry and physiology of the pentose phosphate pathway Stincone 2015 Biological Reviews Wiley Online Library
