WebZ disc) is visible in the centre of the I band. The sarcomereis defined as the region between two Z lines; in relaxed muscle, these are 2.5 to 3.0 µm apart, but they become closer during contraction. The appearance of the sarcomere in longitudinal section is indicated below. Here is a diagram. At rest, the myosin head is bound to an ATP molecule in a low-energy configuration and is unable to access the cross-bridge binding sites on the actin. However, the myosin head can hydrolyze ATP into adenosine diphosphate (ADP) and an inorganic phosphate ion. A portion of the energy released in this reaction changes the shape of the myosin head and promotes it to a high-energy configuration. Through the process of binding to the actin, the myosin head releases ADP and a…
