WebDiffusion rate is directly proportional to the gradient but also depends on the molecule’s lipid solubility, size, degree of ionization, and the area of absorptive surface. Because the cell membrane is lipoid, lipid-soluble drugs diffuse most rapidly. Small molecules tend to penetrate membranes more rapidly than larger ones. WebList and describe 5 different factors that impact the rates of diffusion across a membrane. Movements of Substances: Various substances such as fluids and gases move in and out of the cell...
