Figure аnd infоrmаtiоn belоw is for question 30. In the dаta figure below, two separate groups of cells were each stimulated with a 15-second pulse of isoproterenol (a beta-adrenergic receptor agonist) indicated by the arrow. The result was a time-dependent change in the intracellular cyclic AMP concentration. The ‘Control” group of cells did not receive any other treatment. The experimental group of cells (dashed line) were treated with Drug ‘A’ as indicated by the black bar. Describe a possible ‘mechanism of action’ for Drug A and include in your answer a justification for your choice. (6 points)
