Question

You isolate ATP Synthase (by itself) in solution in a small container. You add ADP to the container, and also add inorganic phosphate and bring the pH of the entire solution to about 7.4. Which of the following do you expect to happen? (circle all that apply) and PLEASE EXPLAIN

a. Nothing in particular

b. ADP is phosphorylated to ATP until all the ADP is used up.

c. Inorganic phosphate is recycled from ADP to ATP and back via the ATP synthase.

d. There will be a pH gradient across the ATP synthase.

e. The ATP synthase will drive photosynthesis.

Explanation / Answer

B . ADP is phosphorylated to ATP until all the ADP is used up : ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi), and needs energy.
