Vedclass · Answer

(A) The thin filament (actin filament) is composed of two $F-actin$ polymers,which are 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.Therefore,the active binding sites for $myosin$ are present on the $actin$ (specifically $F-actin$) molecules.
