Potassium ions are important in the resting membrane potential and the action potential of both nerve and muscle cells.The concentration gradient of potassium ions is critical to both.An excess of potassium outside a neuron or muscle cell would negate the concentration gradient.What would happen if the heart was injected with massive amounts of potassium? Explain your answer.
