A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products.

Skeletal muscle cells are multinucleated because they consist of several cells that have fused together. Muscle cells contain many mitochondria and the characteristic protein filaments(myosin and actin) which are responsible for the muscle contraction. Terminology: the prefix sarco-and myo-both relate to muscle.
any of the cells of skeletal or cardiac muscle tissue. Skeletal muscle fibers are cylindrical polynuclear cells containing contracting myofibrils, across which run transverse striations, enclosed in a sarcolemma.
