As ATP passes certain molecules (just as NADPH) it releases an electron, these electrons' energy provides the necessary energy for the cell.

Homework huh? here ya go :P Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent. Then the ADP is usually immediately recycled in the mitochondria where it is recharged and comes out again as ATP. In the words of Trefil (1992, p. 93) “hooking and unhooking that last phosphate [on ATP] is what keeps the whole world operating.”............... http://www.trueorigin.org/atp.asp
