Explain how the pentose phosphate pathway can respond to a cell’s need for ATP, NADPH, and ribose-5- phosphate.
Answer to relevant QuestionsHow would it affect the reactions of the pen-tose phosphate pathway to have an epimerase and not an isomer-ase to catalyze the reshuffling reactions? What are the similarities and differences between the re-actions catalyzed by pyruvate dehydrogenase and α-ketoglutarate dehydrogenase? Would you expect the citric acid cycle to be more or less active when a cell has a high ATP/ADP ratio and a high NADH/NAD+ ratio? Give the reason for your answer. Calculate E°' for the following reaction: Succinate + 1/2 O2 ( Fumarate + H2O Reflect and apply List the reactions of electron transport that liberate enough energy to drive the phosphorylation of ADP.
