1 Alpha 1 Receptor (PIP2 --> IP3)
1.1 IP3 releases Ca2+ from Sarc. Ret
1.1.1 Ca2+ can enter the cytoplasm through voltage/ligand gated channels
1.1.2 Ca2+ binds to calmodulin
1.1.2.1 Interacts with myosin light chain kinase which P myosin head groups and stimulates contraction
2 B receptors inhibit Myosin Light Chain Kinase
2.1 By activating PKA (though cAMP
