Respuesta :

The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.

The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.

During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.

The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.
