BiologyCellular processes and structureASEdexcel Created by: Harry BarlowCreated on: 05-12-12 19:40 There are 6 types of movement that can occur across a cell membrane. Name them. Diffusion, Facilitated diffusion, Osmosis, Active transport, Exocytosis and endocytosis 1 of 14 What particles are able to diffuse in and out of the cell membrane? Small and/or non-polar lipid soluble molecules e.g. 02, C02 2 of 14 diffusion happens... directly though the PL bilayer 3 of 14 Is it an active or passive form of diffusion? Passive 4 of 14 concentration gradient? Goes down it. 5 of 14 Facilitated diffusion is all about... Channel proteins 6 of 14 How does it work? The channel proteins facilitate the diffusion of polar molecules, charged molecules, and water soluble groups. 7 of 14 Which transport method is all about the diffusion of water across the cell membrane? osmosis 8 of 14 ____ solute conc. to a ____ solute conc. low to high 9 of 14 Osmosis is movement across a ... partially permeable membrane. 10 of 14 Active transport is all about what? carrier proteins. 11 of 14 They can handle every type of substance. Too right they can. 12 of 14 They do not require energy from the breakdown of ATP. Incorrect. 13 of 14 Exo and endo cytosis are all about bulk transport Correct. 14 of 14
