Chloride Ion is Reabsorbed in the Thick Ascending Limb By

Question

Chloride ion is reabsorbed in the thick ascending limb by
A) simple diffusion.
B) facilitated diffusion.
C) active transport.
D) cotransport with Na and K ions.
E) countertransport for bicarbonate ion.

Accepted Answer

In the thick ascending limb of the loop of Henle, chloride ions are reabsorbed primarily through cotransport with sodium (Na) and potassium (K) ions. This process is facilitated by the NKCC2 transporter, which allows these ions to move together across the cell membrane.
