Photosynthetic reactions require NADPH while NADH is involved in aerobic respiration. These two molecules regulate both the biosynthetic and the catabolic activity of the cell. Explain how they do this. Note that NAD+ kinase phosphorylates NAD+ to produce NADPH+.arrow_forward
- Which of the following statements about the pentose phosphate pathway (PPP) is true? (A) The purpose of the pentose phosphate pathway is to produce NADH for use in anabolic pathways and ribose 6-phosphate for nucleotide synthesis.(B) The oxidative arm of the PPP produces (2) NADPH per glucose 6-phosphate that enters the pathway. (C) Phosphopentose isomerase converts the ribose 5-phosphate made in the oxidative arm of the PPP into ribulose 5-phosphate that is used to form the ribose sugar of nucleotides.(D) The non-oxidative arm of the PPP interconverts between ribose 5-phosphate and a variety of intermediates of b-oxidation.
