Vedclass · Answer

(B) The sliding filament theory states that muscle contraction occurs when thin actin filaments slide over thick myosin filaments.During this process,the $A$-band remains constant in length because the length of the myosin filaments does not change.The $I$-band shortens as the actin filaments are pulled toward the center of the sarcomere.The $H$-zone also shortens or disappears.Consequently,the overall length of the sarcomere decreases,leading to muscle contraction.
