Vedclass · Answer

(A) The thin filament (actin) consists of two $F$-actin helically wound to each other. Each $F$-actin is a polymer of monomeric $G$-actin (globular actin) proteins. Two filaments of another protein,$Tropomyosin$,also run close to the $F$-actin throughout its length. $A$ complex protein,$Troponin$,is distributed at regular intervals on the $Tropomyosin$. In the resting state,a subunit of $Troponin$ masks the active binding sites for $Myosin$ on the actin filaments.

Globular protein which masks active sites on $G$-actin is :-
