Consider the Following Two Chemical Equations: A $\rightarrow$ Sucrose + H2O $\Delta$

Consider the following two chemical equations: A.
Glucose + fructose $\rightarrow$ sucrose + H2O, $\Delta$ G = +27kJ/mole (or +6.5 kcal/mole)
B. Glucose + fructose + ATP $\rightarrow$ sucrose + ADP + P_i, $\Delta$ G = -5kJ/mole (or -1.2 kcal/mole)
The free energy change difference between the chemical equations (A) and (B) above is accomplished by:

A) a decrease in activation energy.
B) combining two endergonic reactions.
C) combining an endergonic and an exergonic reaction.
D) combining two exergonic reactions.
E) measuring the reaction rate.
