Consider the following two chemical equations:A

glucose + fructose ? sucrose + H2O, ?G = +27kJ/mole (or +6.5 kcal/mole)
B. glucose + fructose + ATP ? sucrose + ADP + Pi, ?G = ?5kJ/mole (or ?1.2 kcal/mole)
The free energy change difference between the chemical equations (A) and (B) above is accomplishedby: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.
