Phosphate pentose pathway
WebThe pentose phosphate pathway (PPP) is a metabolic pathway that runs parallel to glycolysis. It is a crucial source for NADPH generation for reductive biosynthesis (e.g. fatty acid synthesis) and pentose sugars. The pathway consists of two phases: an oxidative phase that generates NADPH and a non-oxidative phase that involves the ... WebThe pentose phosphate pathway consists of two phases - Phase 2: Non-oxidative phase The first phase consists of three reaction that transform glucose-6-phosphate into ribulose-5-phosphate: Two molecules of NADPH are created in this process The lower the Km = the better the substrate for that particular enzyme (NADH+ much smaller than NAD+) Steps:
