Microbiology Demystified

(Nandana) #1

  1. What kind of reaction performs synthesis and decomposition?
    (a) Endergonic reaction
    (b) Fusion reaction
    (c) Fission reaction
    (d) Exchange reaction

  2. What is the importance of orientation in a chemical reaction?
    (a) Atoms must be in the ideal position when they collide in order to
    have a high probability of bonding.
    (b) All atoms must be in a polar orientation in order for a chemical reac-
    tion to occur.
    (c) All atoms must be in a nonpolar orientation in order for a chemical
    reaction to occur.
    (d) Orientation is of no importance for a chemical reaction to occur.

  3. How does an enzyme increase the likelihood that two atoms will bond?
    (a) An enzyme temporarily moves other atoms away, so it is highly likely
    that collision will occur.
    (b) An enzyme temporarily changes the chemical environment, so it is
    highly likely that collision will occur.
    (c) An enzyme temporarily bonds with an atom to help it move into a
    position where it is highly likely that it will collide and bond with
    another atom.
    (d) An enzyme temporarily changes the pH level, so it is highly likely
    that collision will occur.
