Which of the following is a disadvantage of having lactic acid in the body?

  • AIf it is not broken down, lactic acid can cause pain in the bones.
  • BIf it is not broken down, lactic acid can change the shape of red blood cells.
  • CIf it is not broken down, lactic acid can cause the muscles to become more alkaline.
  • DThere are no disadvantages of having lactic acid in the body.
  • EIf it is not broken down, lactic acid can cause pain in muscles and muscle cramps.


When would the ability of cells to respire anaerobically be an advantage to a human?

  • ADuring short bursts of activity when oxygen intake is limited
  • BDuring long periods of moderate activity when oxygen intake is not limited
