Which of the following statements regarding the structure of contractile proteins are correct ? I. Each actin filaments is made up of two ' F ' actins, which are wound helically around each other. II. Two types of troponins are distributed at regular intervals on the tropomyosin . III. The globular head of meromyosin has binding sites for ATP and troponins. IV myosin is a structure proteins which also has enzymatic activity.

Consider the diagram of thin myofilament. Now, read carefully the statements about molecular arrangement of actin and myosin in the filament. I. Each actin (thin filament ) is made up of 2 F-(filamentous) actins. II. F-actin is the polymer of G-(globular) actin. III. Two-F-actins are twisted into a helix. IV. Two strands of tropomyosin run along the entire length of F-actin. Choose the correct option.

Read the statements regarding muscle proteins (A) Actin is a thin filament and is made up of two F-actins (B) The complex protein, tropomyosin is distributed at regular intervals on the troponin (C) Myosin is a thick filament which is also a polymerized protein (D) The globular head of mermyosin consists of light meromyosin (LMM) Of the above statements
