Explanation:
Muscular tissue is the tissue that is responsible for movement in animals. It is composed of muscle cells, which are specialized cells that are capable of contracting and relaxing. In order to contract, muscle cells require a large amount of energy in the form of ATP (adenosine triphosphate). ATP is a molecule that stores energy in its chemical bonds. When these bonds are broken, the energy is released and can be used by the muscle cell to contract. Muscular tissue has a high ATP requirement because it is constantly contracting and relaxing in order to produce movement.
