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

Question
Transcribed Image Text:Cancer cells need more DNA synthesis but
the NADPH/ NADP* ratio is high. Which of
the following statement is TRUE?
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.
Od. The ribose 5-phosphate is recycled through the
oxidative steps via the nonoxidative reactions and
gluconeogenesis.
