Epinephrine in Liver Cells
General Mechanism:
- Seven Transmembrane-helix (7TM) Receptors
- Binds with alpha-adrenergic receptor
- Initiates Phosphoinositide Cascade
- Release Calcium from Endoplasmic Reticulum (ER)
- Delta subunit of Phosphorylase Kinase is Calmodulin
- Calcium binding leads to partial activiation of Phosphorylase Kinase
