  1. Carbon dioxide is considered a waste product of cellular respiration. True or False?
    TRUE
  2. Glycolysis and the Krebs cycle reactions occur in the mitochondria. True or False?
    FALSE
  3. Which of the following most closely matches the correct order of main events of cellular respiration?
    glycolysis, Krebs cycle, electrons transport system, major ATP production
  4. The metabolic breakdown of one molecule of glucose harvests the greatest amount of energy during what?
    electron transport
  5. When molecules are broken apart in respiration,
    the energy released in respiration is channeled into molecules of ATP
  6. Which of the following liberates the most energy in the form of ATP?
    aerobic respiration
  7. If 2 molecules of glucose are initially present, aerobic respiration will produce how many ATP units overall?
    72
  8. During the Krebs cycle, which of the following choices is NOT one of the overall reactants?
    a.ADP + Pi
    b. NAD+
    c. FAD
    d.ATP *
    e. Acetyl-CoA
    ATP
  9. Which type of energy-releasing pathway evolved first?
    anaerobic
  10. How many carbon atoms does a pyruvate molecule have?
    3
  11. When a cell undergoes mitosis,
    the daughter cells have identical genes and the daughter cell has genes identical to those of the mother cell that produced it.
  12. Which of the following is NOT associated with meiosis?
    somatic cells
  13. Eukaryotic DNA molecules...
    have large amounts of protein dispersed among the DNA molecules.
  14. A portion of a DNA molecules wound around a spool of histone protein is called a...
    nucleosome
  15. In eukaryotic cells, which can occur during the stages of mitosis?
    fragmentation and disappearance of nuclear envelope and nucleolus
  16. The chromatids detach from one another and become visibly separate chromosomes during
    anaphase
  17. Division of the cytoplasm (cytokinesis)
    usually accompanies nuclear division.
  18. The distribution of cytoplasm to daughter cells is accomplished during
    cytokinesis
  19. The cell plate is composed of
    microtubule elements, cellulose, and carbohydrates.
  20. Four of the five answers listed below are events occurring during mitosis. Select the exception.

    a. chromosome replication
    b. division of centromere
    c. lining up of chromosomes at the cellular equator
    d. attachment of spindle microtubules to centromeres
    e. migration of chromosomes to opposite ends of the cell
    chromosome replication
  21. Asexually produced daughter cells are...
    identical to each other and to the parental cell.
  22. Different, or alternative, forms of the same gene are called
    alleles
  23. The essence of meiosis is that
    each gamete receives one member of each pair of homologous chromosomes and gametes are formed that are haploid.
  24. Homologous chromosomes
    • a. may exchange parts during meiosis.
    • b. have alleles for the same characteristics even though the gene expression may not be the same.
    • c. are in pairs, one chromosome of each pair from the father and one from the mother.
    • d. pair up during meiosis.
    • e. all of these
  25. Chromosomes of a pair of homologous chromosomes may differ from other chromosomes in terms of...
    • a. size.
    • b. shape.
    • c. alleles they carry.
    • d. position of the centromere.
    • e. all of these
  26. Chromatids are
    attached at their centromeres and are identical until crossing over occurs.
  27. Meiosis typically results in the production of
    four haploid cells.
  28. Gametogenesis is
    the formation of sex cells.
  29. Which of the following cells is NOT haploid?
    primary oocyte
  30. Four of the five answers listed below are related to pairing of chromosomes. Select the exception.
    interkinesis
