B. There is a problem with his mitochondria and he cannot perform anaerobic respiration.
C. There is a problem with his cell membrane and he cannot transport carbohydrates into his cells.
D. There is a problem with his cell membrane and he transports too many carbohydrates into his cells.

A. Driving the Krebs Cycle
B. Running the Calvin Cycle
C. Breaking down sugar in glycolysis
D. The light-dependent reactions of photosynthesis
E. Accepting the final electron during aerobic respiration

11. When Buster works out too hard in the gym, his muscles go into oxygen debt and produce lactic acid by fermentation. From the muscle cell's point of view, what does this accomplish?

A. This allows the mitochondria to use lactic acid instead of pyruvate.
B. Fermentation recycles NADH into NAD+ so glycolysis can continue.
C. Lactic acid ferments into alcohol, which itself can be used as an energy source.
D. The buildup of lactic acid from fermentation causes pain so Buster will stop.
E. Fermentation supplies NADH to the Krebs cycle so that ATP production can resume.

12. Which of the following statements about cell energetics is true?

A. All eukaryotic organisms do cellular respiration all the time.
B. Plants carry out photosynthesis in order for animals to respire.
C. Plants and fungi carry out photosynthesis instead of respiration.
D. Animals only respire in the day, while plants only respire at night.
E. For plants, the light-independent reactions of photosynthesis are their form of respiration.

21. A group of students studied the effect of light intensity on the rate of a cell process in Elodea plants. The students exposed Elodea plants to different light intensities. A gas was produced by the cell process. The amount of this gas was measured. The rate of the cell process was determined by the amount of gas produced. A graph of the students’ measurements is shown below.
Which of these parts of the Elodea plant cell produces the gas measured in the experiment?

A. Mitochondria
B. Chloroplast
C. Ribosome
D. Nucleus
E. Stroma
