What happens when ATP is broken down in a cell?

• It absorbs energy and becomes ADP and a phosphate.

• It releases energy for the cell to use and becomes ADP and a phosphate.

• It releases energy and transforms into a completely different molecule.

• It absorbs energy and transforms into two molecules of ADP.
