- The reason a heroin addict feels very ill immediately after going "cold turkey" from heroin is likely a result of upregulation of opiate receptors in the postsynaptic cells. upregulation of endogenous opiates. downregulation of opiate receptors in the postsynatic cells. increased postsynaptic receptor sensitivity. downregulation of opiate reuptake transporters.Among the given statements, which ones correctly describe the commonality in dopamine and epinephrine? Select the correct response(s): 10 0 Their formation involves esterification. They are associated with the sensation of pleasure. They are phenolic compounds. They are monoamine compounds. They act as hormones. They are anionic in nature. They are synthesized in the adrenaline glands. They can be synthesized from tyrosine only. They involve a transmethylation reaction in their synthesis.Saved In comparison with first-generation antihistamines, second-generation antihistamines: Multiple Choice are not as effective in antiallergic activity. are not as sedating or drying. have greater anticholinergic activity. are less selective for peripheral H1-receptors.
