Question
Chapter 23, Problem 23.31E
Interpretation Introduction
Interpretation:
The reaction for the step in the citric acid cycle that involves the phosphorylation of GDP is to be written. The structural difference between ATP and GTP is to be stated. The reason as to why GTP can function as a high-energy compound is to be stated.
Concept introduction:
Citric acid cycle is the third stage in the oxidation of food. It begins with two carbon acetyl units. The acetyl units are formed by the oxidation of pyruvate obtained from glycolysis. It is termed as citric acid cycle as the key intermediate in the cycle is citric acid.

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…
Glycerol kinase catalyzes the phosphorylation of glycerol from ATP, yielding glycerol-3-phosphate and ADP. The standard state free energy for hydrolysis of glycerol-3-
phosphate is -9.20 kj/mol and for the hydrolysis of ATP is-30.5 kJ/mol.
Calculate the standard-state free energy change and equilibrium constant for the glycerol kinase reaction at 37 *C.
