Receptor-Mediated Endocytosis

A cellular process where specific molecules are ingested into the cell after they bind to receptors on the cell surface.

Facilitated Diffusion

A process of passive transport, mediated by carrier proteins, allowing molecules to cross the cellular membrane along the concentration gradient without energy expenditure.

Osmotic Pressure

The pressure required to prevent the flow of solvent into a solution through a semipermeable membrane, driven by differences in solute concentration.

Receptor-Mediated Endocytosis

A cellular process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being absorbed.
