How do we get energy?How do we get energy?

By breaking the high-energy By breaking the high-energy bonds between the last two bonds between the last two phosphates in ATPphosphates in ATP

When a When a bond is brokenbond is broken energy is energy is given off, a phosphate is given off, a phosphate is removedremoved

When the phosphate is released When the phosphate is released from ATP the molecule changes from ATP the molecule changes to ADPto ADP

Bond with Energy!!
