adenosine triphosphate (atp) is the intermediate molecule that drives the exergonic transfer of energy to switch to endergonic anabolic reactions used in muscle contraction. this is what causes muscles to work which can require a breakdown, and also to build in the rest period, which occurs during the strengthening phase associated with muscular contraction. atp is composed of adenine, a nitrogen containing base, ribose, a five carbon sugar (collectively called adenosine), and three phosphate groups. atp is a high energy molecule because it stores large amounts of energy in the chemical bonds of the two terminal phosphate groups. the breaking of these chemical bonds in the krebs cycle provides the energy needed for muscular contraction.
