Which of the following is TRUE regarding the signal transduction of smell? (only one response is correct) A. Each glomerulus receives input from a population of olfactory receptor cells responding to a specific odorant molecule B. Chloride moves into the olfactory receptor cell due to its large extracellular concentration C.

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
