Question

Question 1 0.5 pts Balance of electrolytes such as potassium in the blood is tightly controlled by homeostatic mechanisms. This homeostasis can be disrupted in certain disease states, such as hypokalemia (low blood potassium) and hyperkalemia (high blood potassium). Due to the importance of potassium concentrations in controlling the resting membrane potential of a neuron, these imbalances disrupt neuronal firing. Hypokalemia occurs when blood potassium levels are abnormally low. In this case, the resting membrane potential is more hyperpolarized than usual. Clinically, this can lead to fatigue and confusion. Hyperkalemia occurs when blood potassium levels are abnormally high. In this case, the resting membrane potential is more depolarized than usual. In mild clinical cases, this can lead to nausea and muscle cramps. Why is the resting membrane potential value close to the potassium equilibrium potential value? There are many potassium lak channels Voltage-gated potassium channels open in response to depolarization There are no open sodium channels when the membrane is at rest The potassium equilibrium potential is very negative
