1. Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the
metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production?
A. Anaerobic cellular respiration
B. Protein synthesis
C. Aerobic cellular respiration
D. Photosynthesis
2. The diagram below represents the cell cycle.
When cells leave the cell cycle, they exit during G1 phase and then enter the G0 phase, a resting period.
Most normal cells can leave the G0 phase and reenter the cell cycle at G1 phase before entering the S
phase. Cancer cells are different because they cannot enter the G0 phase and are likely to do which of the
following?
A. Fail to complete the S phase
B. Mutate during G1 phase
C. Repeat the cell cycle continuously
D. Die after completing mitosis
3. Which of these must occur during the S phase of the cell cycle so that two daughter cells can be
produced during the M phase?
A. The DNA must be replicated
B. The chromosomes must be joined
C. The cytoplasm must be separated
D. The cell membrane must be expanded

Which phase of mitosis is occurring in the cell indicated by the arrow?
A. Prophase

19. In DNA replication, a strand of DNA is separated and two new DNA strands are synthesized. The cell
has created two biological copies of genetic information from the parent DNA. This process is said to be
semi-conservative because each of the new DNA strands are “half old” and “half new”. Which enzyme is
responsible for binding the two halves together?
A. Glucose
B. DNA Polymerase
C. ATP
D. Fructose
