Which statement is true about cellular respiration?
A. It produces glucose, which provides energy for the cell.
B. It produces ATP, which stores energy that is used by the cell.
C. It produces carbon dioxide, which combines with hydrogen to form sugar.
D. It produces oxygen, which combines with hydrogen to prevent cell poisoning.
B. It produces ATP, which stores energy that is used by the cell.
How are cellular respiration and photosynthesis related, in terms of energy?
A. The energy captured in photosynthesis is used to power cellular respiration.
B. The energy transformed in cellular respiration is used to power photosynthesis.
C. Photosynthesis and respiration perform the same task in terms of energy transformation.
D. Energy is not involved in either photosynthesis or cellular respiration.
A. The energy captured in photosynthesis is used to power cellular respiration.
How does the process of photosynthesis contribute to the carbon cycle?
a) By releasing carbon dioxide into the atmosphere
b) By converting carbon dioxide into organic compounds
c) By absorbing oxygen and releasing carbon dioxide
d) By breaking down glucose into carbon dioxide and water
b) By converting carbon dioxide into organic compounds
When mammals get an infection, their internal body temperature often raises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by...
A. increasing the rate of cellular division
B. decreasing the rate of glucose movement into the cell.
C. increasing the rate of respiration in the mitochondria.
D. decreasing the rate at which CO2 is removed from the cell.
C. increasing the rate of respiration in the mitochondria.
2. In which way are photosynthesis and cellular respiration different?
A. Cellular respiration stores ATP, while photosynthesis releases ATP.
B. Cellular respiration produces oxygen, while photosynthesis uses oxygen.
C. Photosynthesis releases energy, while cellular respiration stores energy.
D. Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
D. Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?
A. The plant will grow faster because it is sheltered from the wind.
B. The plant will die because it does not have oxygen for photosynthesis.
C. The plant will die because it does not have carbon dioxide for photosynthesis
D. The plant will grow at a slower rate because it requires more water.
C. The plant will die because it does not have carbon dioxide for photosynthesis

A. Only species Y is aerobic.
B. Only species Y is anaerobic.
C. Both species X and Y are aerobic.
D. Both species X and Y are anaerobic
B. Only species Y is anaerobic.

Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period. Which of the following statements best explains Mike’s observations?
A. Cells decompose most quickly under the most intense light.
B. Water evaporates from plants faster under the most intense light.
C. Photosynthesis occurs at the highest rate under the most intense light.
D. Gases in the leaves of plants expand most under the most intense light
C. Photosynthesis occurs at the highest rate under the most intense light.
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
A. As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
B. As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
C. The cells will never run out of oxygen if the weightlifter is breathing.
D. As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
A. As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
