6. Plants cells contain both mitochondria and chloroplasts. What outputs of photosynthesis can become inputs for respiration? What outputs of respiration can become inputs of photosynthesis? 7. The rate of photosynthesis was measured for two different plants for varying levels of CO2 (concentration of CO2). Use the graph below to answer the following questions: a. Label the two curves with the enzyme used for initial step of carbon fixation in each plant. b. Which curve has the lowest Km value? What does that tell us about the ability of each enzyme to fix CO2? Rate of Photosynthesis GHOSOSOSOS 40 35 30 25 20 15 10 5 0 -5 O 200 [CO2] 400 c. Based on the graph, which plant would seem to benefit the most from higher levels of CO2 in the atmosphere due to global warming? Why? d. Which plant will better handle rising temperatures due to global climate change? Why? Maize (C₁) Bean (C₂) 600

**Educational Website Transcription** --- 6. **Plant cells contain both mitochondria and chloroplasts. What outputs of photosynthesis can become inputs for respiration? What outputs of respiration can become inputs of photosynthesis?** --- 7. **The rate of photosynthesis was measured for two different plants for varying levels of CO2 (concentration of CO2). Use the graph below to answer the following questions:** a. **Label the two curves with the enzyme used for initial step of carbon fixation in each plant.** b. **Which curve has the lowest Km value? What does that tell us about the ability of each enzyme to fix CO2?** c. **Based on the graph, which plant would seem to benefit the most from higher levels of CO2 in the atmosphere due to global warming? Why?** d. **Which plant will better handle rising temperatures due to global climate change? Why?** **Graph Explanation:** - **X-Axis:** CO2 concentration [CO2] (units not specified) - **Y-Axis:** Rate of Photosynthesis - **Curves:** - **Orange Diamonds:** Represent Maize (C4) - **Blue Squares:** Represent Bean (C3) The graph shows the rate of photosynthesis for Maize (C4) and Bean (C3) at different CO2 concentrations. The Maize curve levels off at a lower CO2 concentration compared to the Bean curve, indicating its efficiency at lower CO2 levels. The Bean curve continues to rise, indicating it benefits from higher CO2 levels. --- *Note: The text and graph shown are part of an exercise intended to analyze photosynthesis rates in different plant types under varying CO2 conditions.*
