1. Calculate ∆G’º of the following enzimatic reactions with 25 ºC y pH 7:
Just as K’eq is a physical constant characteristic for each reaction, so too is ∆G’º a
constant. There is a simple relationship between K’eq and ∆G’º.
∆G’º = -RT ln K’eq
∆G’º = ?
R = 8.315 J/mol K
T = 25°C = 298 K
K’eq = given in the question
a) Glutamate + Oxalacetate → Aspartate + α- Ketoglutarate K’eq = 6.8

Ans: There is a simple relationship between K’eq and...
