The average adult consumes approximately 11,700 kJ per day. Assuming that the metabolic pathways leading to ATP synthesis operate at 50% thermodynamic efficiency, about 5850 kJ ends up in the form of synthesized ATP.

Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body. Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 21.7 mM, 2.17×10-3 mM, and 6.30 mM, respectively. Calculate the weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled. Estimate the free energy of hyrdolysis of creatine phosphate under cellular conditions to determine how many moles are required. Use the standard…
NADH and FADH2 can "create" ATP only if the cell can do electron transport
True
False
Why are some metabolic reactions coupled to the hydrolysis of ATP?
To drive the nonspontaneous reaction
To extend the half-life of enzymes
To increase the equilibrium constant

- To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs. These drugs can each pick up electrons from specific intermediates in the pathway as shown above. You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table. In the presence of drug A, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning. In the presence of drug B, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.arrow_forwardRigor mortis, the stiffening of muscles. after death is due to the depletion of intracellular ATP. Provide the biochemical basis of rigor mortisarrow_forward
