ATP and Muscle Fatigue

ATP and Muscle Fatigue Muscles require energy to contract. Energy is released when biomolecules such as sugars and fats are broken down, and is stored in the form of ATP. ATP enables muscle contraction, but can only be stored in relatively small amounts. For this reason, the body must continually metabolize new ATP molecules. Muscle
