B)sodium ions
C)calcium ions

Question

Quizplus · Accepted Answer

When a membrane is made more permeable to potassium ions, the potassium ions will move out of the cell, causing the cell to become more negative and hyperpolarized. This hyperpolarization will lead to an inhibitory postsynaptic potential (IPSP). In contrast, if the membrane is made more permeable to sodium ions, the influx of sodium ions will depolarize the cell, leading to an excitatory postsynaptic potential (EPSP). Calcium ions play a role in neurotransmitter release but do not directly contribute to membrane potential changes.
