Document Summary

The cell: robert hooke is credited with naming of the cell, antonie van leeuwenhoek discovered unicellular (cid:1684)animals(cid:1685) when examining a drop of water, named these animals: (cid:1688)animalcules(cid:1689) Two classes of cells on earth: prokaryotic, bacteria, structurally simpler. Idp team: 0706 j. braham(id#****649), n. cabanaw (id#****198), z. chan (id#****327), b. corbett (id#****231) Eukaryotic cells contain a large number of parts: compartments: membrane bound structures dedicated to a particular function and components not bound by membranes. Proteins can come together reversibly: membrane assembly and modification, cholesterol regulates membrane fluidity, alters packing and flexibility of lipids. If added to a liquid crystal membrane, fluidity will decrease. If added to a crystalline gel membrane, fluidity will increase. The fluid-mosaic model of biological membranes: fluid: individual lipid molecules move, mosaic: diverse (cid:858)particles(cid:859) penetrate the lipid layer. Structure of biological membranes: fluid-mosaic model, bilayer of amphipathic (having hydrophobic (non-polar) and hydrophilic (polar) regions) lipids, proteins: integral (transmembrane, peripheral, lipid-anchored, components are mobile and can interact.
