Active drug transpo true is all except ?
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.
Energy dependent
Make use of specific transpoer protein
Carrier transpo is nonsaturable
Carries the drug against the concentration gradient
