WebIn addition to its direct role in the cross-bridge cycle, ATP also provides the energy for the active-transport Na + /K + and Ca 2+ pumps. Muscle contraction does not occur without sufficient amounts of ATP. The amount of ATP stored in muscle is very low, only sufficient to power a few seconds worth of contractions. As it is broken down, ATP ... WebAs long as ATP is available, it readily attaches to myosin, the cross-bridge cycle can recur, and muscle contraction can continue. Note that each thick filament of roughly 300 …
