Question: What are the usual ionic forms of ATP and ADP
What are the usual ionic forms of ATP and ADP in typical cells? Does this information have any bearing on the free-energy change for the conversion of ATP to ADP?
Answer to relevant QuestionsA very favorable reaction is the production of ATP and pyruvate from ADP and phosphoenolpyruvate. Given the standard free-energy change for this coupled reaction, why does the following reaction not occur? PEP + 2ADP → ...Consider the structures of arabinose and ri-bose. Explain why nucleotide derivatives of arabinose, such as ara-C and ara-A, are effective metabolic poisons. Pectin, which occurs in plant cell walls, exists in nature as a polymer of D-galacturonic acid methylated at carbon 6 of the monomer. Draw a Haworth projection for a repeating disaccharide unit of pectin with one methylated ...Which reaction or reactions that we have met in this chapter require ATP? Which reaction or reactions produce ATP? List the enzymes that catalyze the reactions that require and that produce ATP. Using the Lewis electron-dot notation, show explicitly the transfer of electrons in the following redox reactions. (a) Pyruvate + NADH + H+ → Lactate + NAD+ (b) Acetaldehyde + NADH + H+ S Ethanol + NAD+ (c) ...
