Question 1

agonists

Answer 1

ligands that cause a postsynaptic affect

Question 2

antagonists

Answer 2

ligands which block the action of the agonist

Question 3

what is the major excitatory neurotransmitter

Answer 3

glutamate (involved in memory and learning)

Question 4

dopamine is involved in

Answer 4

motivation, pleasure, addiction and love

Question 5

serotonin

Answer 5

emotions, wakefulness and temperature regulation

Question 6

what is the major inhibitory neurotransmitter

Answer 6

GABA

Question 7

what is an ionotropic receptor

Answer 7

agonist binds onto a receptor and the agonist itself is an ion channel

Question 8

what is a metabotropic receptor

Answer 8

receptors where ligand binds and it triggers a cascade of reactions that lead to opening or closing of ion channels

Question 9

Answer 12

sodium, potassium and calcium

Question 13

nicotinic ach receptors and composed of how many subunits

Answer 13

5

Question 14

when does ach bind to

Answer 14

the two alpha subunits

Question 15

are GABA and glycine receptors ionotropic or metabotropic

Answer 15

ionotropic (GABAa and GABAc)

Question 16

gaba and glycine receptors are also

Answer 16

pentameric structures

Question 17

are purinergic receptors excitatory or inhibitory

Answer 17

excitatory as they are permeable to cations
