Receptors perform the following function/functions: Ligand recognition, Signal transduction, Both ligand recognition and signal transduction, Disposal of agonists and antagonists.
The following receptor has an intrinsic ion channel: Histamine H1 receptor, Histamine H2 receptor, Adrenergic alfa receptor, GABA-benzodiazepine receptor.
16. Select the receptor that is located intracellularly: Opioid ÎĽ receptor, Steroid receptor, Prostaglandin receptor, Angiotensin receptor.
All of the following serve as intracellular second messengers in receptor mediated signal transduction except: Cyclic AMP, Inositol trisphosphate, Diacyl glycerols, G proteins.
Down regulation of receptors can occur as a consequence of: Continuous use of agonists, Continuous use of antagonists, Chronic use of CNS depressants, Denervation.
