Question

Tubular secretion of hydrogen is directly linked to

a. tubular secretion of potassium.
b. tubular secretion of sodium.
c. tubular reabsorption of potassium.
d. tubular reabsorption of sodium.
e. tubular secretion of chloride.

Answer 1

Tubular secretion of hydrogen is directly linked to the tubular secretion of potassium.a. tubular secretion of potassium.

Step-by-step explanation:

Tubular secretion of hydrogen is directly linked to the tubular secretion of potassium. As per the information provided, the movement of sodium (Na+) out of the tubule is followed by water due to osmotic pressure. The movement of Na+ and water is regulated by hormones, including aldosterone. When aldosterone causes the recovery of Na+ in the nephron, a negative electrical gradient is created that promotes the secretion of K+ and Cl¯ into the lumen, resulting in tubular secretion of potassium.
