7.3: Passive Transport
Diffusion: Random movement of particles to spread out into available space and become equally distributed (eliminate concentration gradients)
-
-
Passive transport: a movement of ions and other atomic or molecular substances across cell membranes without need of energy input
Osmosis: Diffusion of water through selectively permeable membrane into another aqueous compartment containing solute at a higher concentration
-
Facilitated diffusion: Substances impeded by bilayer diffuse passively with help of transport proteins
-
Carrier Proteins: Carrier proteins: Attach to polar substances, change shape to 'shuttle' through
membrane
