It is also loosely bound meaning it can move. 7 of 18 Intrinsic Protein It transport of ions, polar moles, large molecules by using channel proteins and carrier proteins. 8 of 18 Glycoprotein It is carbohydrate chain attached to the extrinsic protein. It works as a receptor and acts as an antigen. 9 of 18 Glycolipids It is a carbohydrate protein attached to the intrinsic protein. It works as a receptor and acts as an antigen. 10 of 18 Cholesterol It maintains the stability of the plasma membrane. 11 of 18 Facilitated Diffusion It is from a high concentration to a low concentration but the transportation of larger molecules or ions. 12 of 18 Active Transport It is the movement of any type of molecules against a concentration gradient 13 of 18 Exocytosis It is a form of bulk transport that relies on fluidity of the membrane requiring ATP. It RELEASES substances from the cells. (moves up) 14 of 18 Endocytosis It is a form of bulk transport that relies on fluidity of the membrane requiring ATP. It TAKES IN substances. 15 of 18 The mosaic model the mosaic model is a representation of the cell membrane structure and is 16 of 18 Concentration gradient The difference in concentration between two areas 17 of 18 Protein A large molecule that is synthesised from amino acids 18 of 18
