Document Summary
When lots of protein cells then lots of ribosomes on er. Smooth/rough er - lipid membranes penetrated by proteins. If rats are given high levels of barbiturates(toxins) lots of smooth er because it has enzyme cytochrome p450 breaks down barbiturates (detoxifying agent) Theory: all membranes are continuous with different proteins in different places and different lipids in different places bilayer matrix that move around -> things closer to make regions district. Golgi -> aka golgi apparatus, golgi body, die lysosome (plants) Stains to an antibody that binds to giantin (protein in golgi) Golgi - got quasi - unstable metals that only precipitated in very specific boundary but stains individual cells (doesn"t cross boundaries) Saw a bunch of fluorescent proteins moving towards the golgi. Cisterna maturation model - vesicles stick together to form a stack that pushes did stack out. Vesicular transport model - vesicles from er fuse into ends of a fixed golgi which are modified and released.
