6 Questions
What are the different types of receptors?
G protein-coupled receptors, Ligand-gated ion channel receptors, Enzyme-linked receptors, Intracellular receptors
Which type of receptors are highly selective targets, with only specific drug structures binding to them?
G protein-coupled receptors
What is the characteristic feature of β-adrenoceptor's structure?
Has transmembrane regions with hydrophilic/lipophilic amino acids folded in plasma membrane
What enables a G protein-coupled receptor like β-adrenoceptor to communicate from the external environment to the internal environment?
Transmembrane regions with hydrophilic/lipophilic amino acids folded in the plasma membrane
Which type of receptors are found in heart, lungs, and liver?
G protein-coupled receptors
What explains why very low concentrations of adrenaline increase heart rate through β-adrenoceptors?
Amplify signals – small number of drug/receptor interactions initiate significant biological effects
