Excretion of potassium is governed primarily by

Question

Excretion of potassium is governed primarily by (A) potassium reabsorption in proximal convoluted tubule (B) potassium secretion in proximal convoluted tubule (C) potassium secretion in distal convoluted tubule (D) potassium reabsorption in distal convoluted tubule

Tardigrade Admin · Accepted Answer

Potassium is reabsorbed by active transport in PCT. However, selective secretion of hydrogen and potassium ions in DCT must influence the excretion of potassium

Q. Excretion of potassium is governed primarily by

potassium reabsorption in proximal convoluted tubule

potassium secretion in proximal convoluted tubule

potassium secretion in distal convoluted tubule

potassium reabsorption in distal convoluted tubule

Potassium is reabsorbed by active transport in $PCT$ . However, selective secretion of hydrogen and potassium ions in $D CT$ must influence the excretion of potassium
