    endergonic
  2. -Chapter 8-
    Most cells cannot harness heat to perform work because
    temperature is usually uniform throughout a cell.
  3. -Chapter 8-
    Which of the following metabolic processes can occur without a net influx of energy from some other process?




    B) 6 CO2 + 6 H2O → C6H12O6 + 6 O2
  4. -Chapter 8-
    If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to
    add more of the enzyme
  5. -Chapter 8-
    Some bacteria are metabolically active in hot springs because
    their enzymes have high optimal temperatures.
  6. -Chapter 8-
    If an enzyme is added to a solution where its substrate and product are in equilibrium, what will occur?
    Nothing; the reaction will stay at equilibrium.
  7. -Chapter 9-
    The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the
    H+ concentration across the membrane holding ATP synthase.
  8. -Chapter 9-
    Which metabolic pathway is common to both fermentation and cellular respiration of a glucose molecule?
    glycolysis
  9. -Chapter 9-
    In mitochondria, exergonic redox reactions
    provide the energy that establishes the proton gradient.
  10. -Chapter 9-
    The final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation is
    oxygen
  11. -Chapter 9-
    What is the oxidizing agent in the following reaction?
    Pyruvate + NADH + H+ → Lactate + NAD+
    pyruvate
  12. -Chapter 9-
    When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs?
    The pH of the matrix increases.
  13. -Chapter 9-
    Most CO2 from catabolism is released during
    the citric acid cycle
  14. -Chapter 10-
    The light reactions of photosynthesis supply the Calvin cycle with
    ATP and NADPH
  15. -Chaper 10-
    Which of the following sequences correctly represents the flow of electrons during photosynthesis?
    H2O → NADPH → Calvin cycle
  16. -Chapter 10-
    How is photosynthesis similar in C4 plants and CAM plants?
    In both cases, rubisco is not used to fix carbon initially.
  17. -Chapter 10-
    ________ can nourish themselves beginning with CO2 and other nutrients that are inorganic.
    Autotrophs, but not heterotrophs
  18. -Chapter 10-
    Which of the following does not occur during the Calvin cycle?
    release of oxygen
  19. -Chapter 10-
    In mechanism, photophosphorylation is most similar to
    oxidative phosphorylation in cellular respiration
  20. -Chapter 10-
    Which process is most directly driven by light energy?
    removal of electrons from chlorophyll molecules
