Microdomains within a plasma membrane that are more grated and concentrated with cholesterol and GPI-anchored proteins to organize a membrane into functional compartments are called _. lipid floats flotsam platforms receptor regions micro phlogistons lipid rafts Match the type of protein and lipid movement in a membrane: The ability of a lipid to slowly flip from one leaf to another The ability of a lipid to stay in the same spot but \'spin\' around The ability of a molecule to quickly move from one location to another within the same leaf lateral diffusion Transverse diffusion Rotation Summarize the primary differences between active and passive membrane transport. Match the following definitions with the appropriate type of transport Spontaneous, unaided movement of a particle from an area of greater concentration to an area of lesser concentration Protein mediated transport for the movement of a particle from an area of lesser concentration to an area of greater concentration, with the use of energy Protein mediated transport of the movement of a particle from an area of greater concentration to an area of lesser concentration The movement of water molecules down its concentration gradient and across selectively a permeable membrane Osmosis Simple Diffusion Facilitated Diffusion Active Membrane Transport Assume that a red blood cell with an internal osmolarity equivalent to 0.15 M NaCI is placed in a solution with a concentrator! of 0.05 M NaCI. Is the solution surrounding the red blood cell considered to be isotonic, hypotonic, or hypertonic to the cell? The solution is compared to the cell. Is the cytoplasm of the red blood cell considered to be isotonic, hypotonic, or hypertonic to the solution surrounding the cell? The cytoplasm is compared to the solution. What should happen to the ceil shape (not change, shrink, or swell) when placed in this solution? A red blood cell would in this solution. Solution 22. Lipid raft 23. A - 2 Transverse diffusion B - 3 Rotation C - 1 Lateral Diffusion 24. Passive transport exchange the molecules based on concentration gradient. It moves from high to low concentration. Examples. Diffusion, Osmosis and facilitated diffusion. Active transport moves a molecules against a concentration gradient so it requires a energy in the form of ATP. It moves solute from low concentration to higher concentration. Examples - Sodium-potassium pump. 25. A - 2 Simple diffusion B - 4 Active membrane transport C - 3 Faciliated Diffusion D - 1 Osmosis 26. A. Hypotonic solution - If external solution is more dilute than cytoplasm is hypotonic solution. B. Hypertonic solution C. Swell - Cells generally swell in hypotonic solution because water try to move inside the cells to make equilibrium to surrounding medium..
