The δ G° values for the hydrolysis of creatine phosphate (creatine-P) and glucose-6-phosphate (G-6-P) are: (i) Creatine-P + - Creatine + P; δ G° = -29.2 kJ; (ii) G-6-P + - Glucose + P; δ G° = -12.4

Question

The δ G° values for the hydrolysis of creatine phosphate (creatine-P) and glucose-6-phosphate (G-6-P) are: (i) Creatine-P + $H_2O$ -> Creatine + P; δ G° = -29.2 kJ; (ii) G-6-P + $H_2O$ -> Glucose + P; δ G° = -12.4 kJ. δ G° for the reaction: G-6-P + Creatine -> Glucose + Creatine-P, is

Prashant Kotian · Accepted Answer

Correct answer: B. Reverse (i): Creatine + P -> Creatine-P + ; dG = +29.2. Add (ii): G-6-P + -> Glucose + P; dG = -12.4. Result: G-6-P + Creatine -> Glucose + Creatine-P; δ G = +29.2 - 12.4 = +16.8 kJ.
