Vedclass · Answer

(B) The process of muscle relaxation occurs in the following sequence:$1$. $Ca^{2+}$ ions are pumped back into the sarcoplasmic reticulum,which leads to a decrease in their concentration in the sarcoplasm $(I)$.$2$. This decrease in $Ca^{2+}$ concentration causes the troponin to move back,resulting in the masking of the active sites on the actin filaments $(III)$.$3$. Due to the masking of active sites,the cross-bridges break,and the $Z$-lines return to their original position $(II)$.$4$. Finally,the muscle fiber returns to its relaxed state $(IV)$.Therefore,the correct sequence is $I \rightarrow III \rightarrow II \rightarrow IV$.

Arrange the following steps of muscle relaxation in the correct chronological sequence:
$I.$ $Ca^{2+}$ ions are pumped back to the sarcoplasmic reticulum.
$II.$ $Z$-lines return to their original position.
$III.$ Masking of actin filaments occurs.
$IV.$ Relaxation of muscles.
