Compare and contrast alpha and beta receptors
What will be an ideal response?
Both alpha receptors and beta receptors are adrenergic receptors on the membranes of target cells. Alpha receptors are more sensitive to NE than beta receptors, but both receptors are stimulated by E. Alpha-1 receptor stimulation typically excites the target cell, and alpha-2 receptor stimulation generally inhibits the target cell. Simulation of beta receptors may result in excitation or inhibition of the target cell.
