MUSCLE FATIGUE HOW DO MUSCLES GET THE ENERGY TO WORK? In muscles‚ it is essential that Calcium is present‚ as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down‚ a phosphate molecule is broken off‚ reducing the phosphate molecules‚ from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal.
