What is actin? Actin is a thin protein filament in muscle fibers that works with myosin for muscle contraction. What is myosin? Myosin is a thick protein filament in muscle fibers that interacts with actin to cause muscle contraction. What is a sarcomere? A sarcomere is the basic contracting unit in a muscle fiber, made of actin and myosin. What is troponin? Troponin is a protein on actin filaments; it binds calcium and helps start muscle contraction. What is the sarcoplasmic reticulum? ...
