Vedclass · Accepted Answer

$Ca^{2+}$

Vedclass · Answer

(B) During muscle contraction,an action potential travels along the sarcolemma and reaches the $T$-tubules,triggering the release of $Ca^{2+}$ ions from the sarcoplasmic reticulum into the sarcoplasm.These $Ca^{2+}$ ions bind to the troponin complex on the thin actin filaments.This binding causes a conformational change in the troponin-tropomyosin complex,which exposes the active binding sites for myosin on the actin filaments.Therefore,$Ca^{2+}$ is the ion that binds with troponin to initiate the cross-bridge cycle.

Which ion binds with troponin during muscle contraction?
