WebATP structure and hydrolysis. Adenosine triphosphate, or ATP, is a small, relatively simple molecule. It can be thought of as the main energy currency of cells, much as money is the main economic currency of human societies. The energy released by hydrolysis (breakdown) of ATP is used to power many energy-requiring cellular reactions. WebChoose 1 answer: A hydrogen atom with a slight positive charge is attracted to a negative charge of another molecule or atom. Two atoms share electrons so they can fill their outer shells. The constant motion of electrons and the creation of charge imbalances bonds two molecules together. One atom loses one or more electrons and the other atom ...
