True for smooth muscle contraction is all excepta) More Latching when lower cross-bridge formation.b) Dephosphorylation causes definite relaxationc) LC phosphatase is essential for binding d) Slow & prolonged contractile response independent of nerve supplye) Length tension relationship does not exist
High-Yield Explanation
Dephosphorylation in smooth muscle does not guarantee relaxation, as some myosin will remain latched to actin.
Light chain phosphatase helps in dephosphorylation, not binding.
