1
Q
Transcellular diffusion
A
the passive movement of drug through lipid membranes. This movement is driven by concentration gradient.
2
Q
Paracellular diffusion
A
The passive movement if drug between cells via tight junctions. This movement is driven by concentration gradient
3
Q
Facilitated diffusion
A
A carrier-mediated process that involves a transport protein which moves drug with a concentration gradient
4
Q
Active transport
A
a carrier-mediated process that requires energy and can move drug against a concentration gradient
5
Q
Endocytosis
A
a process by which a cell engulfs and internalizes a particle
