Vedclass · Answer

(D) Muscle relaxation involves the following steps:$1$. The $Ca^{2+}$ ions are actively pumped back into the sarcoplasmic reticulum,which lowers the cytosolic concentration of $Ca^{2+}$.$2$. Due to the decrease in $Ca^{2+}$ concentration,the $Ca^{2+}$ ions dissociate from troponin.$3$. This causes a conformational change in the troponin-tropomyosin complex,which leads to the masking of the active binding sites on the actin filament.$4$. Consequently,the cross-bridge cycle stops,and the muscle relaxes.$5$. $ATP$ is required for the detachment of the myosin head from the actin filament and for the active transport of $Ca^{2+}$ back into the sarcoplasmic reticulum. Therefore,all three statements are correct.

Relaxation of the muscle takes place due to
$I.$ Pumping of $Ca^{2+}$ ions into the sarcoplasmic reticulum
$II.$ Presence of $ATP$
$III.$ Conformational changes in troponin and masking of the actin filament
