To accomplish movement, we have skeletal muscles.
Muscle contraction requires fuels, one of which is glucose.
In this lecture we will learn how donuts are turned into push-ups. Hydrolysis of ATP to ADP energizes the cross bridges providing the energy for force generation. ATP binding to myosin dissociates the cross bridges bound to actin, allowing the bridges to repeat. ATP is involved in several steps in muscle contraction. Sources of ATP in Skeletal Muscle.
