Which of the following protein prevents contraction by covering binding sites on actin tereby preventing its interaction with myosin?
Tropomyosin molecules lie on top of the active sites of the actin strands, thereby preventing the attraction between the actin and myosin filaments. Ref: Review of Medical Physiology, 23rd Edition By Wiiliam F Ganong; Guyton and Hall Medical Physiology, 10th Edition, Page 71.
