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
Dephosphorylation in smooth muscle does not guarantee relaxation, as some myosin will remain latched to actin.
Light chain phosphatase helps in dephosphorylation, not binding.
