Role of calcium in the phenylephrine-induced activation of phosphorylase “A” in isolated liver cells

The ability of phenylephrine to activate phosphorylase in liver cells with variable degrees of Ca 2+ loading was studied. Phenylephrine has been found to be capable of stimulating phosphorylase at saturating Ca 2+ concentrations that precluded any further action of this ion. Furthermore the degree o...
