Describe what must come together in order for atp to be made

To make ATP, cells must join together ADP & a phosphate using energy from food. A phosphate is removed from an ATP molecule in order to provide energy for the cell. Thus, the ATP molecule turns into an ADP molecule. We eat food which gives us energy to add another phosphate group to the ADP molecule, turning it into an ATP molecule. The cycle then begins again.

Answer: ADP + P + energy

Explanation: to make ATP, cells mush join together ADP and a phosphate using energy from food.
