Question
Chapter 23, Problem 23.59P
Interpretation Introduction
Interpretation:
The reason for NADH to produce 2.5 ATP and FADH2 to produce 1.5 ATP in the electron transport chain needs to be explained.
Concept introduction:
ATP refers to a complex organic molecule that has the ability to provide energy to drive many processes in the living cells such as muscle contraction and chemical synthesis. The term electron transport chain refers to a series of complexes having the ability to transfer electrons between electron donors and electron acceptors via

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…
