Document Summary

Hsp heat shock protein when you heat the cell, you"ll have more of them o when you heat the cell, you denature non covalent bonds breaks protein structure o you always have them you have more when you heat the cell, but you still have them when the cell is at regular temperatures. Singer and nicolson in 1972 termed this the fluid mosaic model o particles are moving around (fluid) o many different types of lipids and proteins (mosaic) o diagram shows one membrane, but one membrane is composed of two layers or leaflets (hence bilayers) Uses: o study lipid properties o membrane protein properties o drug delivery into cells. Golgi apparatus forms a vesicle membrane enclosed compartment o has orange leaflet facing cytosol and black leaflet facing the lumen o does not flip flop stays consistent o as the vesicle fuses into the membrane, it releases the stuff inside to the outside.
