Some cancer drugs work during the cell cycle phase where nuclear and cytoplasmic divisions oc-cur. What is this cell cycle phase called?
 
  a. G1
  b. S
  c. M
  d. G2

Question 2

A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance?
 
  a. Electron-transport chain
  b. Aerobic glycolysis
  c. Anaerobic glycolysis
  d. Oxidative phosphorylation

Answer to Question 1

ANS: C
The M phase includes both nuclear and cytoplasmic divisions. The G1 phase includes the period between the M phase and the start of DNA synthesis. The S phase includes synthesis of DNA in the cell nucleus. The G2 phase includes RNA and protein synthesis.

Answer to Question 2

ANS: C
When no oxygen is available, anaerobic glycolysis occurs. The electron-transport chain is part of the citric acid cycle. Aerobic glycolysis involves the presence of oxygen. Oxidative phosphoryla-tion is the mechanism by which the energy produced from carbohydrates, fats, and proteins is transferred to ATP. It is not part of muscle performance.
