If energy-coupling between the reactions ATP —> ADP and H—> H-P is direct, how many enzymes and

First, we have the reaction ATP -> ADP, which releases energy. Then, we have the reaction H -> H

Question

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? 1. One enzyme, two steps; the enzyme binds ATP and P at the same time. 2. One enzyme, one step; the enzyme binds ATP and P at the same time. 3. One enzyme, one step; the enzyme binds ATP and ADP at the same time. 4. One enzyme, one step; the enzyme binds ATP and H at the same time. 5. Two enzymes, two steps; one enzyme binds ATP and one binds H at the same time. 1 2 3 4 5
