Drugs are transported across a cell membrane by

Question

Quizplus · Accepted Answer

All of the above mechanisms (facilitated diffusion, active transport, and pinocytosis) are involved in the transport of drugs across a cell membrane. Facilitated diffusion allows drugs to pass through the membrane with the help of carrier proteins without energy expenditure. Active transport requires energy to move drugs against their concentration gradient. Pinocytosis involves the engulfing of fluid by the cell, allowing the intake of dissolved drugs.
