The single most important factor influencing potassium ion secretion is .
A)potassium ion concentration in blood plasma
B)intracellular sodium levels
C)the pH of the ICF
D)the potassium ion content in the renal tubule cells

Question

Quizplus · Accepted Answer

The concentration of potassium ions in the blood plasma is the single most important factor influencing potassium ion secretion. When potassium ion concentration in the plasma is high, it stimulates the secretion of potassium ions into the filtrate by the cells lining the renal tubules. Conversely, when plasma potassium ion concentration is low, there is less secretion of potassium ions into the filtrate.
