Name: _____________________________________ Key Terms: Photosynthesis Chloroplast Glucose Chemosynthesis Respiration Aerobic Anaerobic Mitochondria Glycolysis Fermentation Testing Your Knowledge: 1. Write the equation for photosynthesis once using chemical symbols and a second time using words. Label the reactants and products. 6CO2 + 6H2O 6 carbon dioxide + 6 water C6H12O6 + 6O2 Glucose + 6 oxygen 2. Write the equation for cell respiration once using chemical symbols and a second time using words. Label the reactants and products. C6H12O6 + 6O2 Glucose + 6 oxygen 6CO2 + 6H2O 6 carbon dioxide + 6 water 3. What do you notice about the two equations? The equations are the same, just backwards. Photosynthesis produces the reactants of respiration (glucose and oxygen). Respiration produces the reactants of photosynthesis (carbon dioxide and water). 4. Explain how photosynthesis and respiration are involved in the carbon cycle. Photosynthesis removes carbon from the atmosphere (in the form of carbon dioxide). Respiration contributes carbon to the atmosphere (in the form of carbon dioxide). 5. Describe factors that may affect the rate of photosynthesis. Sunlight, availability of water and carbon dioxide 6. Describe factors that may affect the rate of respiration. Availability of oxygen and energy (chemical energy in the form of glucose) 7. Compare aerobic and anaerobic respiration. Which is more efficient? Aerobic respiration requires oxygen. Anaerobic respiration does not require oxygen. Aerobic respiration is more efficient. Name: _____________________________________ 8. Which organelle is involved in photosynthesis? Respiration? Photosynthesis takes place in the chloroplast. Respiration takes place in the mitochondria. 9. What types of organisms use aerobic respiration? Anaerobic respiration? Animals use aerobic respiration. Bacteria and yeasts use anaerobic respiration. 10. What are the types of anaerobic respiration? Alcoholic fermentation Lactic acid fermentation
