BIO 162 Chapter Notes - Chapter 10,39: Leghemoglobin, Light-Independent Reactions, Flavonoid
Document Summary
Co2 is fixed during the calvin cycle. explain what the term fixed means in this context. Describe how the current atmosphere differs from that in which photosynthesis evolved. Identify the ways in which photorespiration drains energy from the plant. Diagram all reactions of c4 and cam photosynthesis shown in class. Pay particular attention to steps in which energy is consumed or fixation occurs. Predict the relative success of c3, c4 and cam plant in a cool, wet environment and in a hot, dry environment. Distinguish between temporal and spatial separation of co2 fixation and sugar synthesis (c4, cam, C4 and cam photosynthesis are described as co2 pumps. how do these forms of photosynthesis differ from c3 and why should they be characterized as pumps? * In c4 and cam plants rubisco always operates under conditions of elevated co 2.
