Question: Consider a cell that requires much more ribose 5 - phosphate than NADPH. The cell needs ribose 5 - phosphate but has a relatively high

Consider a cell that requires much more ribose5-phosphate than NADPH. The cell needs ribose 5-phosphate but has a relatively high concentration of NADPH and a low concentration of NADP ?+. These conditions may occur in rapidly dividing cells.
What is the fate of glucose 6-phosphate, glycolytic intermediates, and pentose phosphate pathway intermediates in this cell?
Under the given conditions, all triose phosphates are converted to pyruvate by the glycolytic pathway.
Most of the glucose 6-phosphate enters the pentose phosphate pathway.
The oxidative pentose phosphate pathway reaction catalyzed by glucose 6-phosphate dehydrogenase is slowed down.
Most of the glucose 6-phosphate enters the glycolytic pathway and is converted to frucitose 6-phosphate and glyceraldehyde 3-phosphate.
Conversion of glycolytic intermediates to ribose 5-phosphate requires transketolase and transaldolase.
Three molecules of glyceraldehyde 3-phosphate and two molecules of fructose 6-phosphate are used to generate five molecules of ribose 5-phosphate.
