Questions and Answers
  • 1. 
    True or False Cellular respiration is a complex series of chemical reactions that harvests the energy trapped in the bonds of glucose sugar molecules and converts it into a chemical form that can be stored for later use.
    • A. 

      True

    • B. 

      False

  • 2. 
    True or False Cellular respiration is critical for the survival of most organisms because the energy in glucose will never be used by the cells until it is stored in molecules of ATP.
    • A. 

      True

    • B. 

      False

  • 3. 
    True or False Anaerobic cellular respiration occurs in the presence of oxygen.
    • A. 

      True

    • B. 

      False

  • 4. 
    True or False Glucose is the only requirement for cellular respiration to take place.
    • A. 

      True

    • B. 

      False

  • 5. 
    True or False Cellular respiration transfers/converts about 60% of the energy of glucose to ATP.
    • A. 

      True

    • B. 

      False

  • 6. 
    True or False Compared to other energy conversion processes, cellular respiration is very inefficient in converting energy to a usable form.
    • A. 

      True

    • B. 

      False

  • 7. 
    True or False To control the release of heat, cells build up and break down most molecules in a linked series of small reactions called metabolic pathways that release only a little bit of heat energy at a time.
    • A. 

      True

    • B. 

      False

  • 8. 
    True or False Cellular respiration not only protects the cell from lethal temperature increases but also provides the cell with a mechanism for transfering the energy of glucose to ATP in a controlled manner.
    • A. 

      True

    • B. 

      False

  • 9.

      False

  • 11. 
    True or False In glycolysis, a glucose molecule is broken down to 2 three-carbon molecules called pyruvate.
    • A. 

      True

    • B.

  • 14. 
    True or False Most glycogen storage-related diseases result from the absence of certain enzymes needed in the breakdown of glycogen to glucose.
    • A. 

      True

    • B. 

      False

  • 15. 
    True or False A single human brain cell uses an estimated 10 million ATP molecules per second to carry out its tasks. 
    • A. 

      True

    • B. 

      False

  • 16. 
    True or False The NADH and FADH2 molecules act like specialized delivery trucks that dump off their loads of electrons and H+ ions for conversion to ATP via the electron transport chain.
    • A. 

      True

    • B. 

      False
