Cellular Respiration & Photosynthesis Review

A student places a plant in a closed container. The student then places the container in a dark room and measures the amount of carbon dioxide the plant produces over several hours. Which of the following processes is this investigation most likely designed to measure?

• cellular respiration

• diffusion

• mitosis

• decomposition

What is the relationship between photosynthesis and cellular respiration?

• The products (outputs) of photosynthesis are the reactants (inputs) of cellular respiration.

• Some organisms perform photosynthesis but all organisms do cellular respiration.

• The purpose of photosynthesis is to convert light energy into chemical energy (glucose).

• The purpose of cellular respiration is to transfer the energy stored in glucose to another molecule called ATP.

• All of the above is/are correct

A student places four small aquatic snails in a test tube containing bromothymol blue solution. The solution will change color from blue to yellow if the carbon dioxide level increases. The student seals the test tube and notes that the solution is blue. After a few hours, the student observes that the solution is yellow.

What cellular process did the snails perform that caused the color of the solution to change?

• Cellular respiration

• Cellular digestion

• Fermentation

• Photosynthesis

In the ocean, some bacteria break down oil instead of glucose for energy. There is often a low concentration of oxygen in the areas where these bacteria are found.

Which of the following statements best explains why the oxygen concentration is often low where these bacteria are found?

• The bacteria develop cell nuclei in the presence of the oil.

• The bacteria perform a process similar to photosynthesis with the oil.

• The bacteria use oxygen and release carbon dioxide as they break down the oil.

• The bacteria make their membranes more permeable to oxygen as they break down the oil.

Mammals store extra glucose in the form of a compound called glycogen.

Which molecule supplies the energy needed to join glucose molecules together to form a molecule of glycogen?

• ATP

• Oxygen

• RNA

• Carbon Dioxide

Carbon monoxide is a poisonous gas because it competes with the gas that binds to hemoglobin in red blood cells.

Which of the following would be most directly affected by carbon monoxide poisoning?

• Fat digestion

• Cellular respiration

• Breakdown of wastes

• Protein Synthesis

Plants in floodplains often get covered by water during floods. Some plants survive the floods because they can continue photosynthesis underwater. However, the plants’ rates of photosynthesis are much lower underwater than above water.

Which of the following helps to explain why the rates of photosynthesis are lower underwater than above water?

• There is too much oxygen in the water.

• There is no carbon dioxide in the water.

• The available light is less intense underwater.

• The chloroplasts do not function underwater.
