1.	What will be the best definition for “carrier”?(a) Nonpolar drugs can be transported through carrier-mediated transport(b) Carrier binds reversibly and no covalently with the molecules(c) It discharges the molecules and gets destroyed itself(d) The carrier is a proteinI had been asked this question by my school teacher while I was bunking the class.Enquiry is from Mechanisms of Drug Absorption in division Absorption of Drugs of Drug Biotechnology
Answer» Correct answer is (b) Carrier binds reversibly and no covalently with the MOLECULES The explanation: The carrier-solute COMPLEX can cross the membrane to REACH the other site where the carrier DISCHARGES the solute and RETURNS back to its position. The carriers carry polar charged molecules and are mostly enzymes.
