Document Summary
Bio 1090 review: cell size 10-3 meters. Structurally simplier does not mean worse at surviving: plants cells: have chloroplasts and cell walls, electron microscopy: electrons increase resolution, properties, complex and organized, genetic- coded activity, reproduce division, energy, engage in mechanical activities. Compartments: membrane bound structures dedicated to a particular function. Divides a seduction sequesters keep contents from mixing with each other. Amphipathic: having both hydrophobic and hydrophilic regions. Nature of lipids in membrane unsaturated lipids increase fluidity saturated lipids reduce fluidity temperature. Warming increases fluidity = liquid crystal cooling decreases fluidity = crystalline gel. Balance between ordered(rigid) and disordered structure allows: Membrane assembly and modification dynamic interactions between membrane components. It also alters packing and flexibility of lipids. If added to crystalline gel, fluidity will increase. If added to a liquid crystal, fluidity will decrease. Lipid anchored: proteins attach to the lipid bilayer. Peripheral: membrane proteins associate with the surfaces of the lipid bilayer.
