Question

What will happen to hydrocarbons after all phosphate are removed from ATP

Answer 1

When one phosphate group is removed from ATP, ADP is created.
Explanation:
ADP is adenosine di -phosphate, and is an adenosine molecule attached to two phosphate molecules.
(ATP is adenosine tri -phosphate, and is an adenosine molecule attached to three phosphate molecules.)
ATP would have more energy, as energy is created when a bond is broken. Thus, energy is released when the phosphate is broken off from ATP to form ADP.
