3.
Imagine the following reaction happening at room temperature under standard
conditions:
A → B
a. What is the value of the AG° that results in equal amounts of A and B at
equilibrium?
b. What is the change in AG° required to produce a 10 fold increase in the
equilibrium constant?
c. Let us assume that the reaction above has AG° of +12.5 kJ/mol. What is the ratio
of product to substrate at equilibrium?
d. Expanding on (c), let us couple this reaction to the hydrolysis of ATP (AG°=-30.5
kJ/mol):
A + ATP + H20 → B + ADP + P;
AG° = -18 kJ/mol
