Some of these muscles help to express your emotions through gesticulation and facial expressions, while the heart beats more than 3.3 billion times over 80 years! In a relaxed cell, myosin is in a high energy state (cocked) but is unable to bind actin due to tropomyosin covering the myosin binding site. With access to our simulations, you will have hundreds of hours of engaging, high-quality learning content available to you. The three types of skeletal muscle fibers are slow red oxidative fibers, fast intermediate oxidative-glycolytic fibers and fast white glycolytic fibers.
