Answer» Answer: The Sarcomere: The Basic Contractile UNIT of Muscle A sarcomere is the basic contractile unit of muscle fiber. Each sarcomere is composed of two main protein filaments—actin and myosin—which are the active structures responsible for MUSCULAR CONTRACTION. The most popular model that describes muscular contraction is called the sliding FILAMENT theory. In this theory, active force is generated as actin filaments slide past the myosin filaments, resulting in contraction of an individual sarcomere. Explanation: please Mark at Brainliest answer |
