How does ATP facilitate energetic coupling? The hydrolysis of ATP reduces the activation energy necessary to synthesize the final molecule of a reaction The hydrolysis of ATP increases the potential energy of the molecule that gets phosphorylated The hydrolysis of ATP decreases the Gibbs Free Energy necessary for the final reaction to occur The hydrolysis of ATP makes the first step of energetic coupling endergonic

If energy-coupling between the reactions ATP ---> ADP and H---> H-P is direct, how many enzymes and how many steps are required, and how is coupling accomplished? A) One enzyme, two steps; the enzyme binds ATP and P at the same time. B) One enzyme, one step; the enzyme binds ATP and P at the same time. C) One enzyme, one step; the enzyme binds ATP and ADP at the same time. D) One enzyme, one step; the enzyme binds ATP and H at the same time. E) Two enzymes, two steps; one enzyme binds ATP and one binds H at the same time.
