- 1. Multiple ChoiceHow are cellular respiration and photosynthesis related, in terms of energy?The energy captured in photosynthesis is used to power cellular respiration.The energy transformed in cellular respiration is used to power photosynthesis.Photosynthesis and respiration perform the same task in terms of energy transformationEnergy is not involved in either photosynthesis or cellular respiration.
- 2. Multiple ChoiceIn which way are photosynthesis and cellular respiration different?Cellular respiration stores ATP, while photosynthesis releases ATP.Cellular respiration produces oxygen, while photosynthesis uses oxygen.Photosynthesis releases energy, while cellular respiration stores energy.Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
- 3. Multiple Choice
The diagram shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.
Which statement describes how photosynthesis and cellular respiration are interrelated?Oxygen is produced during cellular respiration and stored during photosynthesis.Carbon dioxide and water released by cellular respiration are used in photosynthesis.Photosynthesis releases the energy that is stored during the process of cellular respiration.Glucose is used during cellular respiration to produce food that is broken down during photosynthesis. - 4. Multiple ChoiceA diagram representing the relationship between photosynthesis and cellular respiration is shown.
The numbered boxes in the diagram represent which of the following?1 - water; 2 - nitrogen1 - nitrogen; 2 - oxygen1 - oxygen; 2 - carbon dioxide1 - carbon dioxide; 2 – water - 5. Multiple ChoiceTwo test tubes were filled with a solution of bromthymol blue. A student exhaled through a straw into each tube, and the bromthymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?Oxygen was produced by photosynthesis.Carbon dioxide was removed by photosynthesis.Carbon dioxide was produced by respiration.Oxygen was removed by respiration.
- 6. Multiple ChoiceWhich gas is removed from the atmosphere during photosynthesis?hydrogenoxygennitrogencarbon dioxide
- 7. Multiple Choicepotted 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?The plant will grow faster because it is sheltered from the wind.The plant will die because it does not have oxygen for photosynthesis.The plant will die because it does not have carbon dioxide for photosynthesisThe plant will grow at a slower rate because it requires more water.
- 8. Multiple ChoiceMike 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?Cells decompose most quickly under the most intense light.Water evaporates from plants faster under the most intense light.Photosynthesis occurs at the highest rate under the most intense light.Gases in the leaves of plants expand most under the most intense light - 9. Multiple ChoiceWhich of the following are the reactants of photosynthesis?water and glucoseglucose and carbon dioxidecarbon dioxide and wateroxygen and water
- 10. Multiple ChoiceWhich process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?photosynthesislactic acid fermentationaerobic respirationalcoholic fermentation
- 11. Multiple ChoiceIf a plant died from lack of food, which structure is most likely missing or damaged?flowerrootstemleaves
- 12. Multiple ChoiceWhich of the following structure is where photosynthesis occurs in the cell?nucleuschloroplastmitochondriaendoplasmic reticulum
- 13. Multiple ChoiceTwo different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?Only species Y is aerobic.Only species Y is anaerobicBoth species X and Y are aerobic.Both species X and Y are anaerobic.
- 14. Multiple Choice
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?
As the cells run out of oxygen they switch to anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
The cells will never run out of oxygen if the weightlifter is breathing.
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.
- 15. Multiple ChoiceWhich of the following structure is where cellular respiration occurs in the cell?nucleuscytoplasmmitochondriavacuoles
- 16. Multiple ChoiceWhat function does ATP carry out in living things?aids in protein folding and coilingused to capture and transfer energyidentifies DNA start sequences for transcriptionhelps maintain the fluidity of cell membranes
- 17. Multiple ChoiceWhich process do the animals in the food web use to convert energy from food into ATP?cellular respirationosmosisphotosynthesistranscription
- 18. Multiple ChoiceCarmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music.
Which component is missing from Carmen’s experiment?a questiona hypothesisa control groupa description of the experiment - 19. Multiple ChoiceWhich of the following equations best represents photosynthesis?C + O2 + H2O = CO2 +HOH6CO2 + 6H2O = C6H12O6 + 6O26C + 6 H2O = C6H12O6C6H12O6 = 6CO2 + 6H2O
- 20. Multiple ChoiceWhy are there less air bubbles as the plant is place further away from the light sourcebecause cellular respiration decreases when there is less lightbecause the light independent reaction decreases when there is less lightbecause photosynthesis decreases as a plant is moved further away from a light sourcethe wavelength increases as a plant is placed further away from a light source
- 21. Multiple ChoiceOne of the principal compounds that living things use to store energy isDNAATPH20CO2
- 22. Multiple ChoiceTwo different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?Only species Y is aerobic.Only species Y is anaerobicBoth species X and Y are aerobic.Both species X and Y are anaerobic
