Transport depends on $Na^+$ transport.

Vedclass · Answer

(D) In the nephron,the reabsorption of $K^+$ (Potassium) is closely linked to the transport of $Na^+$ (Sodium).Specifically,in the proximal convoluted tubule $(PCT)$,the reabsorption of $Na^+$ creates an electrochemical gradient that facilitates the passive reabsorption of $K^+$.Furthermore,in the distal convoluted tubule and collecting duct,$K^+$ secretion is actively coupled with $Na^+$ reabsorption via the $Na^+-K^+$ pump.Therefore,the transport of $K^+$ is fundamentally dependent on the mechanisms governing $Na^+$ transport.
