Sch Photosynthesis and Cellular Respiration Test Review Questions
1. Are plants heterotrophic or autotrophic?
a. autotrophic
2. Organisms that obtain chemical energy from other organisms are called what?
a. heterotrophs
3. The portable energy in the cell or “cash in hand” is known as what?
a. ATP
4. What is the major light-absorbing pigment in photosynthesis?
a. Chlorophyll (a and b)
5. What wavelengths of light are absorbed by chlorophyll?
a. Red and blue
6. T or F: The dark reaction cannot take place during the day.
a. False- they are not dependent upon light
7. CO2 + H2O → C6H12O6 + O2 is the equation for what process?
a. Photosynthesis
8. What are some factors that can affect the rate of photosynthesis?
a. Temperature, CO2 concentration, Sunlight
9. T or F: As light intensity increases, the rate of photosynthesis will increase indefinitely?
a. False- because eventually the leaf will light on fire (per David), level off
10. Glucose is broken down into 2 pyruvates during the first stage of cellular respiration. This process is called
what?
a. Glycolysis
11. If oxygen is present it is known as what type of respiration?
a. Aerobic
12. If oxygen is not present it is known as what type of respiration?
a. Anaerobic or Fermentation
13. During aerobic respiration, the breakdown of 1 molecule of glucose will make how many ATP?
a. 38
14. During anaerobic respiration, the breakdown of 1 molecule of glucose will make how many ATP?
a. 2
15. Most of the energy used by life on Earth comes from where?
a. Sun
16. Where do heterotrophs get their energy?
a. Other organisms, cellular respiration
17. How do autotrophs get their energy?
a. The sun, photosynthesis
18. Light energy is converted into chemical energy through what process?
a. Photosynthesis
19. What is the major atmospheric by-product of photosynthesis?
a. oxygen
20. When electrons of a chlorophyll molecule are raised to a higher energy level they enter what?
a. Electron transport chain
21. During photosynthesis, the series of reactions that create the carbohydrates needed for energy and growth are
called what?
