Myofibrils are constructed of overlapping

WebMyofibrils are constructed of overlapping strands of protein polymers known as which of the following? Actin and tropomyosin Tropin and myosin Tropoactin and myosin Actin … WebThe myosin and actin filaments overlap and slide past each other when muscles contract and relax. The Z line separates one sarcomere from the next and is also where actin filaments attach. Other areas of the sarcomere are defined by the presence or absence of acting and/or myosin.
