What is the function of K⁺ ion in the body?

Question

Quizplus · Accepted Answer

K⁺ ion is actually K+ ion (potassium ion) which is important in establishing the resting membrane potential in cells. This means it is involved in maintaining the normal electrical charge across the cell membrane, which is necessary for nerve and muscle function. The other options provided are incorrect. A is incorrect because potassium ions are actually involved in decreasing the acidity of body fluids. C is incorrect because aldosterone secretion is mainly regulated by the renin-angiotensin-aldosterone system and not directly by K+ ions. D is incorrect because K+ ions are involved in maintaining a hypertonic intracellular fluid and not a hypotonic fluid. E is incorrect because the depolarization of action potentials is mainly caused by sodium (Na+) ions, not potassium ions.
