Correct Answer – B
Ans: B. Aquaporin 2
- Principal cells of collecting duct contain a regulated system of water channels antidiuretic hormone (ADH, also called arginine vasopressin, AVP).
- ADH controls permeability of these cells to water by regulating insertion of pre-formed water channels (aquaporin-2, AQP2) into apical membrane.
