Which carrier pump is transpoing solutes in thick ascending limb of Henle loop?: (A) Carrier pump Na-K-2Cl transpoer., (B) NaCl- cotranspoer, (C) Na2+-H+ exchanger, (D) Na2+-K+ exchanger
Answer is A. Carrier pump Na-K-2Cl transpoer. REABSORPTION IN THICK ASCENDING LIMB: Sodium, Potassium & Chloride reabsorption: By "Secondary active transpo" - Through Na2+-K+-2Cl-- carrier transpoer. Transpos one Na2+, one K+, & two Cl-. Active sodium absorption occurs. 30% filtered Na2+ reabsorbed. Ref: Guyton 12th Ed.
