Sucrose #(C_12H_22O_11)# doesn't store any energy itself. In order for it to get release energy, it must be first broken down into glucose #(C_6H_12O_6)#. Then, the glucose is broken down into pyruvate #(CH_3COCOO^-)# and then into #ATP#, where it contains lots of energy that can be used either immediately or stored.
Even if we want to use the energy from #ATP#, it also must be broken down into #ADP#, but the loss of a phosphate bond releases lots of energy for the cells to use.
