Running, like any sustained skeletal … WebThis work requires energy. Muscles get energy from ATP molecules made during the process of cellular respiration. During continuous activity, the muscles begin to use up their energy supply and oxygen and start to accumulate waste products. As a result, the muscles become fatigued, losing their ability to contract. WebATP, motor motor proteins, and actin microfiliament tracks are essential for contraction of eukaryotic muscle. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion.
