Text Solution

Verified by Experts

The correct Answer is:

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