Cancer cells need more DNA synthesis but the NADPH/ NADP* ratio is high. Which of the following statement is TRUE? a. Flux through the oxidative reactions is low and the nonoxidative reactions are reversed in order to form ribose 5-phosphate. O b. The oxidative reactions and the isomerase supply both ribose 5-phosphate and NADPH with little flux through the nonoxidative branch. O c. Flux through the oxidative reactions increases and ribose 5-phosphate is shunted into glycolysis by the nonoxidative reactions. d. The ribose 5-phosphate is recycled through the
