    D: Triple Bonds

    E: Double and triple bonds
    Double and triple bonds
  2. This stabilizes membranes, affecting fluidity and reducing permeability

    B: Cholesterol
    C: Ribosomes
    D: Stability Proteins
    Cholesterol
  3. This Protein is responsible for Desmosomes

    A: Attachment Proteins
    B: Receptor proteins
    C: Recognition Proteins
    D: Transport Proteins
    Attachment Proteins
  4. The fluid mosaic model describes membranes as fluid because

    A: the phospholipids and proteins move from place
    to place within the bilayer
    B: the phospholipid molecules are bonded to one another, making them more moveable

  8. True/False: The first law of thermodynamics states that systems tend to increase in entropy
    False
  9. True/False: An enzyme can act as a catalyst, is a protein, increases the activation energy, and any type of substrate can bind to one enzyme.
    False
  10. The following picture is an example of a(n)
    Exergonic Reaction
  11. What causes the active site to
    change shape, so the substrate
    no longer fits?

    A: Allosteric inhibitor
    B: Enzyme adapter
    C: Noncompetitive inhibitor
    D: Competitive inhibitor
    Noncompetitive inhibitor
  12. Which of the following does NOT illustrate kinetic energy?

    A car moving at 55 mph
    B: A 100 watt light bulb, turned on
    C: A drop a water falling down a waterfall
    D: A 9 volt battery
    A 9 volt battery

    A: Lower the activation energy of a reaction
    B: Give the reaction an active site for it to occur
    C: Regulate how many times a reaction occurs
    D: Lower the energy of the product.
    Lower the activation energy of a reaction
  14. What is the correct order of an enzymatic reaction?
    1: The Enzyme binds the substrates
    2: Enzyme and products are floating in solution
    3: The enzyme binds the products
    4: The enzymes and substrates are floating in solution
    4,1,3,2
  15. Air pores in the backs of leaves where CO2 is obtained is called. . .
    Stomata
  16. True/False: Photosystem II occurs before Photosystem I
    True
  17. True/False: The Calvin cycle is part of the light reactions
    False
  18. Which of the following is NOT a step of chemiosmosis

    A: H+ flow down concentration gradient through a thylakoid channel protein called ATP synthase, generating ATP from ADP

    B: Glucose may then be converted to the disaccharide sucrose or linked to form starch (a storage molecule) or cellulose (a major component of plant cell walls)
    C: As the energized electron travels along electron chains, some of the energy it liberates is used to pump hydrogen ions into the thylakoid space
    D: This pumping creates a high concentration of H+ inside the space relative to the surrounding stroma
    Glucose may then be converted to the disaccharide sucrose or linked to form starch (a storage molecule) or cellulose (a major component of plant cell walls)
  19. Which of the following is used for carbon fixation?
