Study the following statements about myosin monomers1) Many meromyosins constitute one thick filament2) The globular head is an active ATPase enzyme3) The tail part is called heavy meromyosin4) The head and short arm projects outwards at regular distance is known as cross armIn the above how many statements are true?

The tail of myosin is made of light meromyosin (LMM).Each myosin (thick) filament is also a polymerised protein. Many monomeric proteins called Meromyosins constitute one thick filament. Each meromyosin has two important parts, a globular head with a short arm and a tail, the former being called the heavy meromyosin (HMM) and the latter, the light meromyosin (LMM).The HMM component, i.e.; the head and short arm projects outwards at regular distance and angle from each other from the surface of a polymerised myosin filament and is known as cross arm.
