Facilitated Diffusion
A process of passive transport, helped by integral membrane proteins, where molecules move across a biological membrane from higher concentration to lower concentration without needing cellular energy.
Phagocytosis
The process by which a cell engulfs solid particles to form an internal compartment known as a phagosome.
Exocytosis
A cellular process in which substances are expelled from a cell through the fusion of vesicles with the plasma membrane.
Active Transport
The energy-dependent process of moving molecules across a cell membrane against their concentration gradient, often involving specific transport proteins.
