Questão 1
Questão
If a drug speeds up the reuptake of a neurotransmitter, it's an
Responda
-
antagonist
-
agonist
Questão 2
Questão
If a drug disrupts the production of a neurotransmitter, it's an
Responda
-
agonist
-
antagonist
Questão 3
Questão
What effect on APs would a glutamate agonist have?
Responda
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
Questão 4
Questão
What effect on APs would a GABA agonist have?
Responda
-
More action potentials (an increase in excitability)
-
Less action potentials (a decrease in excitability)
-
Neither, because GABA doesn't influence excitability

Questão
Label the steps of an action potential
Responda
-
Resting potential
-
Na+ ligand-gated channels open
