  3. Isotonic solution
  4. Cell Membrane Function: A Biological Barrier
  5. Transport proteins
  1. a Know and be able to label a phospholipid bilayer diagram
  2. b have 3-D shapes that make them highly selective, recognizing atoms or molecules by shape, size or charge.
  3. c a cell membrane prevents many materials from entering the cell.
  4. d receptors, like antennae, detect specific compounds or cells and bind with them, triggering endocytosis.
  5. e has the same solute concentration on both sides of the cell membrane. Equilibrium has been reached. EQUAL FLOW of water into and out of the cell

5 Multiple Choice Questions

  1. ...
  2. the movement of only certain substances across the cell membrane
  3. Cell membranes are semi-permeable allowing some materials to cross, while excluding others. They can select a) by particle size
    - small enough to enter membrane - O2 H2O
    - too large to cross - sugar
    b) particular materials to transport across (they bind to chemicals based on their size shape or charge)
  4. all matter is made of tiny particles
  5. a) carrier proteins - facilitate the diffusion of glucose across the cell membrane
    b) channel proteins - have tunnel-like pores filled with water that allow charged ions in and out of the cell

5 True/False Questions

  1. Membranes at Work 3. Controlled Delivery of Medicationsfilters toxic wastes that accumulate in the blood while retaining necessary proteins, glucose, amino acids & ions

          

  2. Cell Membrane Function: ApoptosisCell membranes are semi-permeable allowing some materials to cross, while excluding others. They can select a) by particle size
    - small enough to enter membrane - O2 H2O
    - too large to cross - sugar
    b) particular materials to transport across (they bind to chemicals based on their size shape or charge)

          

  3. Two types of Endocytosis:a) carrier proteins - facilitate the diffusion of glucose across the cell membrane
    b) channel proteins - have tunnel-like pores filled with water that allow charged ions in and out of the cell

          

  4. Three Types of Passive Transport 3.Facilitated Diffusionthe net movement of particles from an area of high concentration to an area of low concentration
    - no energy is expended
    - in a cell very small particles can cross the cell membrane by moving between the phospholipid molecules
