9.2 receptor types

Question 1

a receptor that binds to hydrophobic ligands that can easily cross the plasma membrane to enter the cell

Answer 1

intracellular receptors

Question 2

a receptor that binds to hydrophilic ligands outside of the cell

Answer 2

cell surface or membrane receptor

Question 3

type of membrane receptor that has a gated ion channel to allow specific ions to pass through the central pore

Answer 3

channel-linked receptors

Question 4

type of membrane receptor that is an enzyme activated by the binding of a ligand (almost all are protein kinases)

Answer 4

enzymatic receptor

Question 5

type of membrane receptor that interacts with G-proteins to control the functions of effector proteins

Answer 5

G protein-coupled receptors

Question 6

G protein can activate

Answer 6

enzyme or ion channel

Question 7

small molecules or ions that alter the behavior of cellular proteins by binding to them and changing their shape

Answer 7

second messengers

Question 8

cyclic adenosine monophosphate (cAMP) and calcium ions

Answer 8

two types of common second messengers
