Question

Quizplus · Accepted Answer

The oxidative branch of the pentose phosphate pathway generates NADPH and ribose 5-phosphate. However, when there is a higher demand for NADPH than ribose 5-phosphate, the non-oxidative branch is favored to generate NADPH through recycling of intermediates. On the other hand, if there is a higher demand for ribose 5-phosphate, then the oxidative branch predominates to generate more of this intermediate for nucleotide synthesis. Therefore, when there is a higher demand for NADPH than ribose 5-phosphate, the oxidative branch of the pathway predominates.
