5 Multiple choice questions

  1. the proteins of a membrane that are not embedded in the lipid bilayer; they are appendages loosely bound to the surface of the membrane, often exposed to parts of the integral proteins; attached by cytoskeleton on cytoplasmic side, and by fibers of ECM on extracellular side
  2. in an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.
  3. The experimental factor that is being measured; the variable that may change in response to manipulations of the independent variable
  4. elements-C,H,O(1:2:1)
    polymer-polysaccharides, complex carbs
    fuction-provide energy
  5. internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified
