What will happen if a neuron membrane suddenly becomes permeable to chloride ions?
A)Chloride ions will enter the neuron,and the membrane potential will become more negative.
B)Chloride ions will enter the neuron,and the membrane potential will become more positive.
C)Chloride ions will exit the neuron,and the membrane potential will become more negative.
D)Chloride ions will exit the neuron,and the membrane potential will become more positive.

Question

Quizplus · Accepted Answer

Chloride ions have a negative charge, so if they enter the neuron, they will contribute to a more negative membrane potential. This is because the resting membrane potential is more negative than the equilibrium potential for chloride ions. As a result, the membrane potential will become more negative.
