Vedclass · Answer

(A) The contraction of striated muscles is explained by the $Sliding 	ext{ } Filament 	ext{ } Theory$. According to this theory, muscle contraction occurs when thin actin filaments slide over thick myosin filaments. This process is facilitated by the formation of cross-bridges between the myosin heads and the actin binding sites, which pull the actin filaments towards the center of the $A$-band (the $M$-line), thereby shortening the sarcomere.
