A sarcomere (Greek sarx flesh, meros part) is the basic unit of striated muscle tissue. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers) which are formed in a process known as myogenesis. Muscle fibers are composed of tubular myofibrils.he myosin head also binds to ATP, which is the source of energy for muscle movement. Myosin can only bind to actin when the binding sites on actin are exposed by calcium ions. Actin molecules are bound to the Z line, which forms the borders of the sarcomere. Other bands appear when the sarcomere is relaxed.
  The sarcomere is the contractile unit. It is the space between two Z discs that contains one group of myosin fillaments and two groups of actin fillaments, one group on â¦ each end of the myosin fillaments.Z discs join sarcomeres together end-to-end to form myofibrils.hat is the contractile unit of muscle? already exists. already exists as an alternate of this question. exists and is an alternate of.
