The non-oxidative stage of the pentose phosphate pathway ________.

Question

Quizplus · Accepted Answer

The non-oxidative stage of the pentose phosphate pathway consists entirely of near-equilibrium reactions, meaning that the reactions are reversible and the pathway can operate in both directions. This stage involves interconversion of sugars using enzymes such as transketolase and transaldolase, and does not directly produce NADPH or consume ATP. However, it can generate NADPH indirectly by producing sugars that can be converted to ribose-5-phosphate, which can then enter the oxidative stage of the pathway to produce NADPH. There are no reactions in the non-oxidative stage that are allosterically inhibited by NADPH.
