An example is eye movements. (*describe how?). ( which displaces tropomyosin, thus exposing myosin binding site in skeletal muscle contraction) myosin light chain kinase catalyzes transfer of phosphate from ATP to regulatory light chain of myosin, allowing the head to bind actin, and myosin binds actin - sliding filaments.

This can occur through resistance exercises. Smooth muscle cells have different diameters when cut in cross section because of their spindle-shape. cardiac muscle tissue uses aerobic respiration almost exclusively to avoid fatigue Compare a 3D model of a sarcomere to its electron micrograph and observe the changes that take place during contraction and relaxation.
