Each myosin molecule of sarcomere is composed of
Two monomers
Four monomers
Six monomers
Eight monomers
Sarcomeres are the fundamental contractile unit of skeletal muscle and are characterized by their highly ordered appearance under a polarizing light microscope.Thick filaments in the A band are composed primarily of the protein myosin. Each myosin molecule is composed of six monomers: two protein strands intewined in a helical arrangement (termed heavy chains) and four smaller, globular proteins (termed myosin light chains).Thin filaments are composed of three primary proteins: actin, tropomyosin, and troponin.
