The energy produced by a spontaneous reaction is often used to provide the energy to drive nonspontaneous reactions. For example, the conversion of ATP to ADP in our cells acts as the energy source for the nonspontaneous reactions that combine amino acids during protein synthesis. Here is the conversion of ATP to ADP: ATP(aq) + H,O ADP(aq) + HPO,² (aq) AG° = -30.0 kj/mol A typical reaction combining two amino acids during protein synthesis has a AG = 15.0 kJ/mol. What is the minimum ATP concentration required to provide the energy to combine 1 mole of amino acid synthesis (total energy = 15.0 kJ)? Assume that the concentration of ADP = 9 µM (micromolar) and HPO4²- = 4 mM (millimolar).

The energy produced by a spontaneous reaction is often used to provide the energy to
drive nonspontaneous reactions. For example, the conversion of ATP to ADP in our
cells acts as the energy source for the nonspontaneous reactions that combine amino
acids during protein synthesis. Here is the conversion of ATP to ADP:
ATP(aq) + H,O = ADP(aq) + HPO,²-(aq)
AG° = -30.0 kj/mol
A typical reaction combining two amino acids during protein synthesis has a AG = 15.0
kJ/mol. What is the minimum ATP concentration required to provide the energy to
combine 1 mole of amino acid synthesis (total energy = 15.0 kJ)?
Assume that the concentration of ADP = 9 µM (micromolar) and HPO42- = 4 mM
(millimolar).
