Write true or false. If false change the statement so that it is true. (a) Actin is present in thin filament
Explanation During the mechanism of muscle contraction, each and every muscle fiber has parallel filaments or myofilaments which have alternate dark and light bands in it. These bands are due to the presence of two proteins which are named as actin and myosin. Actin is present in the thin filament and myosin is present in the thick filament. Final answer It is true that actin is present in the thin filament.
