Document Summary

Block 3 - lecture 7 - making parts of a cell. This is where the critical role of the er and golgi come into play for making and moving parts (proteins). Evolution of er ==> invagination of plasma membrane. The invagination of the plasma membrane may have taken place because the cell would benefit from the increase in surface area and maintenance of particles on the surface. The membrane"s lipid bilayer structure is similar to the plasma membrane. Rough: has ribosomes on surface (ribosomes stich together the proteins) Vesicle packages of proteins from er move to golgi via cis face --> golgi then modifies, sorts, and packages raw proteins --> vesicle packages of more specialized proteins exit golgi via trans face. Psio303a page 1 packages raw proteins --> vesicle packages of more specialized proteins exit golgi via trans face. Particles can migrate from the er to fuse with golgi body (fuses at cis face of golgi)
