Question
answer i
![If 0.1 M glucose 1-phosphate is incubated with phosphoglucomutase, the glucose 1-
phosphate is converted to glucose 6-phosphate. At equilibrium, the concentration of
glucose l-phosphate is 4.5 x 103 M and that of glucose 6-phosphate is 8.6 x 102 M.
Calculate Keq' and AG for this reaction (assume it is in the direction of glucose 6-
phosphate formation). T= 298 K, R= 8.315 J/K/mol.
Glucose 1- phosphate + Glucose 6-phosphate
(ii)
Consider the following reaction:
Acetoacetate + NADH + H* + B-hydroxybutyrate + NAD*
The reduction of acetoacetate by NADH is a coupled redox reaction.
The half- reactions are:
Acetoacetate + 2 H" + 2e + B-hydroxybutyrate
E"= - 0.346V
NAD* + H* + 2e + NADH
Eo=- 0.315V
Calculate AE and AG for this reaction at 25°C when [acetoacetate] and [NADH] are
10 mM and 9 mM respectively, and [B-hydroxybutyrate] and [NAD*] are 1 mM and
1.ImM respectively.
