1 Name: Quiz name: Cellular Respiration & Photosynthesis Review Date: 1. You are able to live on Earth due to which waste product of photosynthesis? A carbon dioxide B water C sugar D oxygen 2. Organisms that can produce their own food are called A autotrophs B all bacteria C humans D heterotrophs 3. Suppose a farmer decides to build a greenhouse using green-tinted glass instead of clear glass. Why is this a bad idea? A Photosynthesis will occur at a much slower rate because green light is reflected by plants rather than absorbed. B The green-tinted glass will trap too much heat, causing the plants to wilt and die. C The green part of the spectrum of sunlight will not be transmitted through the glass panes, causing the plants to miss this important source of light energy. D The green light will trigger overproduction of CO2 by the plants, slowing the rate of photosynthesis. 4. Which of the following is NOT a necessary input for the process of photosynthesis A carbon dioxide B water C oxygen D energy 5. Which of the following can be used to measure the rate of photosynthesis? A light intensity B temperature C carbon dioxide level D oxygen production 6. Which colors of following light rays are most useful in photosynthesis? A green and red B blue and green C blue and red D red and violet Page 1 of 7

2 7. You are a greenhouse manager. Your greenhouse currently has 40% light intensity and a 3% concentration of CO2. Which of the following actions will increase the rate of photosynthesis for the plants in your greenhouse? A decrease the CO2 level, decrease light intensity B increase the CO2 level, decrease light intensity C decrease the CO2 level, increase light intensity D increase the CO2 level, increase light intensity 8. A caterpillar eats an oak leaf. Which of the following BEST describes the energy transfer in this situation? A Both the caterpillar and the leaf gain energy. B Energy is transferred from the leaf to the caterpillar. C Decomposers in the leaf obtain energy from the caterpillar. D The oak tree gains energy when the caterpillar eats the leaf. 9. The molecule ATP is composed of elements found in organic molecules. Which of the following is one of these elements? A aluminum B calcium C phosphorus D tin 10. Which of the following occurs during photosynthesis? A CO2 is used to produce water. B CO2 is absorbed by mitochondria. C CO2 and H2O are converted to carbohydrates. D CO2 and H2O are combined into carbonic acid. 11. All organisms have ways to produce ATP. Which of the following statements describes why ATP is a critical compound for all cells? A It causes mitosis to begin. B It is an energy-transfer molecule. C It is a major component of cell membranes. D It carries information from DNA to ribosomes. 12. Which element is the main component of all organic molecules? A carbon B nitrogen C potassium D sodium 13. In a sealed tank is a large sprig of Elodea and a snail. The tank is kept for several weeks on a sunny window sill. Both the plant and snail live and appear to be healthy. Why does this happen? A The snail produces oxygen, and the plant produces carbon dioxide. B Both the snail and the plant produce oxygen. C The snail produces carbon dioxide, while the plant produces oxygen. D Both the snail and plant produce carbon dioxide. Page 2 of 7

3 14. Which of the following are high energy electron carriers produced during the Kreb cycle? A ETC B NADH & FADH2 C ATP D XYZ 15. In cellular respiration, the most energy is produced in which step?
