Question
Chapter 31, Problem 13P
Interpretation Introduction
Interpretation:
The energetic equivalent of 2 ATP molecules is used to activate one amino acid, but only 1 ATP molecule is used. The reason for this statement should be determined.
Concept introduction:
ATP (adenosine monophosphate) is an organic molecule and the chemical that provides energy to the cell. Muscular contractions, chemical synthesis, and nerve impulse propagation, all these activities are run by ATP derived energy. It is synthesized in the mitochondria; therefore, mitochondria istermed as the powerhouse of the cell.

At body temperature (37°C), k of an enzyme-catalyzed reaction is 2.3X10¹⁴ times greater than k of the uncatalyzed reaction. Assuming that the frequency factor A is the same for both reactions, by how much does the enzyme lower the Eₐ?
The ΔG°′ for hydrolytically removing a phosphoryl group from ATP is about twice as large as the ΔG°′ for hydrolytically removing a phosphoryl group from AMP (−14 kJ · mol−1). Explain the discrepancy.
