Question

When a neuron is at rest, the concentration of is greater in the neuron's

nearby extracellular fluid relative to its intracellular fluid. If we were to increase

the concentration of in the extracellular fluid, the neuron would ultimately

• Ca2+; Na+; hyperpolarize

• Na+; K+; lose its capacity to generate an action potential

O K+; Na+; lose its capacity to generate an action potential

• CI-; K+; hyperpolarize

Answer

K+; Na+; lose its capacity to generate an action potential

When a neuron is at rest, the concentration of K+ is greater in the neuron's nearby extracellular fluid relative to its intracellular fluid. If we were to increase the concentration of K+ in the extracellular fluid, the neuron would ultimately lose its capacity to generate an action potential due to the increased outward flow of K+ ions.
