Vedclass · Answer

(B) The proteins troponin and tropomyosin are closely associated with actin filaments. Troponin is a complex of three polypeptide subunits: $T_{n}C$,$T_{n}I$,and $T_{n}T$. Specifically,$T_{n}T$ binds to tropomyosin,$T_{n}I$ binds to actin,and $T_{n}C$ binds to $Ca^{2+}$ ions. Therefore,troponin is attached to tropomyosin on the actin filament.
