BIOL 130 Lecture Notes - Lecture 16: Cytosol, Eukaryote, Nucleosome
Document Summary
Objective: draw a cross section of the plasma membrane. Things can dissolve and move through the hydrophobic region, but this is not too common. Integral protein- any protein that extends into the membrane. Peripheral protein- just touch the outside of the membrane. Known as the fluid mosaic model- phospholipids are unsaturated so its fluid and it has different types of proteins with different functions. Objective: list six functions of membrane proteins and describe examples of each: transport. Intercellular joining- intercalated disks used for a more permanent interaction. Mice subjected to hiv did not get infected: something present on human cells that allowed this fusion to occur but absent in mouse cell, something in mouse cell that prevented fusion, protein _____________ Objective- make drawings of diffusion, facilitated diffusion, active transport across biological membranes and give examples of each: molecules, bacteria/viruses/large complexes of molecules (bulk transport)
