1. a molecule of atp has phosphate groups attached to it. when the cell needs energy, it converts atp into. when the cell is able to store energy, it converts to.

Answer

Brief Explanations:

ATP (adenosine - tri - phosphate) has 3 phosphate groups. When the cell needs energy, ATP is hydrolyzed to ADP (adenosine - di - phosphate) and a phosphate group, releasing energy. When the cell can store energy, ADP can combine with a phosphate group to form ATP again.

Answer:

  1. 3
  2. ADP and a phosphate group
  3. ADP
  4. ATP
