About this document
Membrane Transport Mechanisms Explained by Arvin is a document available to read on EtoBox.
Particles move across membranes through four main methods: simple diffusion, facilitated diffusion, osmosis, and active transport. Simple diffusion and osmosis involve passive movement of particles down a concentration gradient without cell energy expenditure. Active transport requires cellular ATP and includes processes such as endocytosis and exocytosis. Vesicles transport materials within cells between organelles like the Golgi and ER.
