lecture 4- cell membrane transport

QuestionAnswer
Describe the characteristics of a phospholipid bilayer water soluble compounds unable to pass through. important for maintaining Intra celluar fluid.
what is 4 characteristics of a membrane? -isolation -regulates enviromental exchange -sensitivity -structural support
membrane carbohydrates: proteogycans, gyloproteins, glycolipids and glycocalyx.
Membrane proteins integral membrane - encased in membrane. Transmembrane protiens. Peripherial proteins - inner or outter surface of membrane,
Describe how proteins contribute to the structure and function of the cell membrane Anchoring proteins –stabilise the cell Recognition proteins –immune response Enzymes –Peripheral and integral Channels –Gaps in membrane –Allows movement of water and ions –Molecule specific
Explain why the cell membrane is more permeable to lipid soluble substances and small molecules than to large water-soluble substances
Describe how the following mechanisms facilitate the transport of substances across cell membranes: –diffusion –osmosis –facilitated diffusion –active transport –endocytosis –exocytosis endocytos- pinocytosis- cell drinking phagocytosis - cell eating
Describe the effects of isotonic, hypertonic and hypotonic solutions on cells Isotonic solution(equal) –Same solute concentration inside cell vs outside Hypotonic solution (expand) –Solute concentration inside cell highe rvs outside Hypertonic solution (shrivel) –Solute concentration inside cell lower vs outside
Describe how carbohydrates contribute to the structure and function of the cell membrane –Lubrication and protection –Anchoring and locomotion –Specificity and binding –Recognition
