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 […]

Muscle Fatigue Muscle contractions are essential for muscles to function properly. The inability of a muscle to maintain tension is muscle fatigue. Failure to contract may occur because of the accumulation of lactic acid, a lack of ATP, or decreased blood flow. In this exercise, you will investigate the correlation between repeated movements and muscle
