Photosynthesis and Respiration Review

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy?

• A. It is used to reform ADP.

• B. It is converted to heat energy.

• C. It is stored as glycogen in the liver.

• D. It is converted to a smaller carbohydrate.

This diagram shows an experimental setup containing an aquatic plant, elodea, gas collection equipment, and a light source. Which gas bubbles are being collected?

• carbon dioxide, because it is a waste product of photosynthesis

• water vapor, because it is a waste product of photosynthesis

• nitrogen, because it is a waste product of photosynthesis

• oxygen, because it is a waste product of photosynthesis

During the light reactions of photosynthesis, energy becomes stored in the compounds ATP and NADPH. A second set of reactions uses this stored energy to produce vital compounds such as glucose. This second set of reactions involves a biochemical pathway known as

• the Calvin cycle.

• carbon fixation.

• photorespiration.

• photosystem I.
