Select the correct option regarding A, B and C

Select the correct option regarding A, B and C Select the correct option regarding A, B and C

Options

  1. AA-Tropomyosin-runs close to F-actin throughout its length
  2. BB-Troponin-complex protein distributed at regular interval of tropomyosin
  3. CC-F actin - polymer of monomeric G-actin helically bound to each other
  4. DNone of these

Correct answer

C. C-F actin - polymer of monomeric G-actin helically bound to each other

Step-by-step solution

A - Troponin B - Tropomyosin C−FC-F-actin Two filaments of protein tropomyosin run close to F-actins 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.
