Outward projection of the head region of meromyosin

Vedclass · Answer

(B) The cross arm consists of the outward projection of the head region of meromyosin.Each myosin (thick filament) is a polymerized protein consisting of many monomeric proteins called meromyosin.Each meromyosin has two important parts: a globular head with a short arm and a tail.The globular head with the short arm is called Heavy Meromyosin $(HMM)$,while the tail is called Light Meromyosin $(LMM)$.The $HMM$ component,which includes the head and the short arm,projects outwards at regular distances and angles from the surface of the polymerized myosin filament; this structure is known as the cross arm.The globular head acts as an active $ATPase$ enzyme and contains binding sites for $ATP$ and active sites for actin.
