Question

an inhibitory neurotransmitter might cause ____________. a sodium gates to open into the cell b potassium gates to open moving potassium out of the cell c sodium and chloride gates to open into the cell d chloride gates to open moving chloride out of the cell

Explanation:

Inhibitory neurotransmitters typically cause hyperpolarization of the postsynaptic membrane. When potassium gates open and potassium moves out of the cell or chloride gates open and chloride moves into the cell, the inside of the cell becomes more negative, leading to hyperpolarization. Option A would lead to depolarization as sodium influx makes the cell more positive. Option C with sodium influx would depolarize. Option D is incorrect as chloride should move into the cell for inhibitory effects. When potassium moves out of the cell due to potassium - gate opening, it contributes to hyperpolarization which is an inhibitory effect.

Answer:

B. potassium gates to open moving potassium out of the cell
