Document Summary

Membranes and transport ch 7. 1-7. 5: membrane structure, id phospholipid structure, id fluid mosaic model. Membrane transport: cc passive and active transport. Bulk transport: cc exocytosis and endocytosis, membrane structure, phospholipid, principle component. 3. structure fig 5. 11: bilayer formation, due to (1) roughly cylindrical shape (2) strongly amphipathic nature, held together primarily by hydrophobic interactions (1) shield tail. s from aqueous environment. 4. fig 7. 2: fluid - mosaic model fluid. 1: phospholipids - move laterally within on layer of membrane. Membrane transport: selectively permeable, passive transport cell does not expand metabolic e. Bulk transport - large molecules input of e from cell - atp. A: active transport - but not carrier mediated, exocytosis contents released from cell, vesicle containing wastes or secretory products fuses with plasma membrane. 2: primary mechanism for plasma membrane growth. 4. fig 7. 9 step 4: endocytosis, material taken into cell by forming vesicles derived from plasma membrane.
