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:

1. Calculate ?G’º of the following enzimatic reactions with 25 ºC y pH 7: a) Glutamate + Oxalacetate ? Aspartate + a- Ketoglutarate K’eq = 6.8 b) Dihydroxyacetone phosphate ?...
