Select the total number of true statements from the following.

(1) Each myosin (thick) filament is also a polymerized protein.

(2) Many monomeric proteins called meromyosins constitute one thick filament.

(3) 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 is called the light

meromyosin (LMM).

(4) 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 polymerized myosin filament and is known as cross arm.

(5) The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for actin.
