<prompt> Active drug transpo true is all except ?Energy dependentMake use of specific transpoer proteinCarrier transpo is nonsaturableCarries the drug against the concentration gradient  <response>: Ans. is c i.e., Carrier transpo is nonsaturable Active transpo As the name suggests active transpo is active pumping of drug molecules through a membrane against concentration gradient by a molecular pump carrier mediated, which requires energy to function. So, active transpo has following characteristics: Movement is against concentration gradient A molecular pump carrier protein is required. Energy is required.
