Document Summary

There is a basic structure according to the fluid mosaic model. Fluid because the proteins inserted into the membrane are free to move within the membrane. Phospholipid bilayer: lipid component as a barrier for diffusion of materials across the membrane. Stick of butter hydrophilic end group facing water and hydrophobic faces away. Constitutes membrane proteins expand in the membrane (protein that consist of amino acids) Materials from extracellular can pass through the core of the channel or can be carriers out of the cell. Phospholipid bilayer: peripheral proteins: , involved in attachment functions, shape changes . Mainly inside the cell: cytoskeleton: anchors to pm; can also interact with receptors (eg: ??) Interacts with receptors and is capable of movement when acted on by other factors. Can give the cell mobility: glycocalyx: ensemble of carbohydrates attached to lipids & proteins on extracellular face; It a sugar based barcode that gives the cell a certain identity.
