Consider the following two chemical equations: A. glucose + fructose → sucrose + H2O, Δ G = +27 kJ/mole (or +6.5 kcal/mole) B. glucose + fructose + ATP → sucrose + ADP + Pi, Δ G = −5 kJ/mole (or −1.2 kcal/mole) The overall free energy change in 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.
