Question

Questions 32 and 33 refer to the following scenario: A cell containing a high concentration of CO2 is placed into a solution containing a high concentration of O2.  The concentration of CO2 in the cell is equal to the concentration of O2 outside the cell.

 

  1. What will happen to the O2 in the solution? a) It will be actively transported into the cell, moving down its concentration gradient.  b) It will diffuse into the cell, moving down its concentration gradient. c) It will not move because it can’t cross the cell membrane. d) It will not move because there is as much CO2 in the cell as O2 outside it. e) none of the above

 

  1. Subsequent to what happened (if anything) in #7, some sugar is added to the solution in which the cell resides. Which of the following statements is true? a) The cell is now in an isotonic solution. b) The cell is now in a hypertonic c) The cell is now in an hypotonic d) The cell is exergonic e) The cell is endergonic
