Cell Energy Worksheet
Answer the following questions:
Cellular respiration:
• What is cellular respiration and what are its three stages?
• What is the role of glycolysis? Include the reactants and the products. Where does it occur?
• What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur?
• What is the role of the electron transport system? Include the reactants and the products. Where does it occur?
Photosynthesis:
• What is the overall goal of photosynthesis?
• Because photosynthesis only occurs in plants, why is it essential to animal life?
• What is the role of the light reactions? Include the reactants and the products. Where does it occur?
• What is the role of the Calvin cycle? Include the reactants and the products. Where does it occur?
Summary:
• Explain how photosynthesis and cellular respiration are linked within ecosystems.
• Visit the NASA website (http://data.giss.nasa.gov/gistemp/graphs_v3/) and research global temperature changes. How has global warming affected overall temperatures? What effects do cellular respiration and photosynthesis have on global warming?
