Question 21

(Multiple Choice)

For the hydrolysis of ATP to ADP + ℗ᵢ,the free energy change is -7.3 kcal/mol under standard conditions (1 M concentration of both reactants and products).In the cellular environment,however,the free energy change is about -13 kcal/mol.What can we conclude about the free energy change for the formation of ATP from ADP and℗ ᵢ under cellular conditions?


A)It is +7.3 kcal/mol.
B)It is less than +7.3 kcal/mol.
C)It is about +13 kcal/mol.
D)It is greater than +13 kcal/mol.
E)The information given is insufficient to deduce the free energy change.
