• Diffusion Through a Membrane: Diffusion is the net movement of particles (atoms, molecules, or ions) from a highly concentrated region to a region of low concentration. Understanding diffusion through a membrane is a key biology concept. Take this interactive tour to help you master the process and terminology.
• Endocytosis: Endocytosis is a cellular process where cells absorb molecules or substances from outside the cell by engulfing it with the cell membrane. This tutorial explains the cellular processes involved in endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosis.
• Exocytosis: Exocytosis is the cellular process by which cells excrete waste products or chemical transmitters. Learn about this process in this tutorial.
• Lipid Bilayer: The lipid bilayer is an organic compound that is insoluble in water but soluble in nonpolar solvents, providing the basic impermeable structure of the membrane. Explore the process, structure, and function of an plasma membrane's lipid bilayer with this interactive tutorial.
