Question
Chapter 28, Problem 28.59P
Interpretation Introduction
Interpretation:
Phosphoenolpyruvate (PEP) has a high-energy phosphate bond that has more energy than the anhydride bonds in ATP. Determine the step of the glycolysis, which suggests the same.
Concept Introduction:
PEP is a very essential intermediate in glycolysis as well as gluconeogenesis. It is important for the formation of the ATP from the ADP as it has a phosphate bond with highest energy, which is easily transferred to the ADP.

If sugar must be broken down to release energy through cellular respiration, why is
ATP needed in the process? Explain.
Kinases are enzymes that catalyze the addition (or removal) of a phosphate group to ( or from) a substance. ATP is also involved. How many kinases are in glycolysis? Name them.
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…

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.

(Hint: It is NOT the same reason.)arrow_forwardTrypanosomes living in the bloodstream obtain all their free energy from glycolysis. They take up glucose from the host’s blood and excrete pyruvate as a waste product. In this part of their life cycle, trypanosomes do not carry out any oxidative phosphorylation, but they do use another oxygen-dependent pathway, which is absent in mammals, to oxidize NADH. Would this pathway be necessary if the trypanosome excreted lactate rather than pyruvate? Explain.arrow_forward
