1. Cellular Respiration1 Photosynthesis - Chapter 8 Topics you are responsible for This chapter goes into much more detail than for what you will be responsible. Thus, the outline of these powerpoint slides and the question bank will be guides to what you should understand. You won’t be responsible for the details of bacterial photosynthesis, energy processing in reaction centers, the enhancement effect, or the specific steps of the electron transport. However, be sure to read about the properties of light and the absorption properties of different pigments. End of Chapter questions: Understand: all Apply: all Synthesize: all Do all mQuiz questions

2. Cellular Respiration2 Where does photosynthesis occur? Chloroplast structure Inner and outer membranes Thylakoids -- granna

3. Cellular Respiration3 What are the characteristics of the photosynthetic pigments? Chlorophyll and carotenoids Light harvesting complexes -- light absorbing pigments -- Reactions Centers e- Resonation

4. Cellular Respiration4 What are the two stages of Photosynthesis? Light dependent reactions vs Light independent reactions = “Calvin- Bensen cycle”

5. Cellular Respiration5 The L-D reactions 2 “Photosystems” PSII & PSI Electron transport plastoquinone cytochrome b6-f plastocyanin ATP synthesis via Photo-phosphorylation

6. Cellular Respiration6 What do different depictions of the L-D reactions show? Z-scheme Membrane arrangement Virtual Cell Photosynthesis

7. Cellular Respiration7 How are ATP and NADPH used to convert (fix) CO 2 into organic molecules? Calvin-Bensen Cycle -- 3 stages Calvin cycle CO 2 Fixation Carbon Reduction RUBP Regeneration RUBP carboxylase/ Oxygenase -- “Rubisco” “C3” photosynthesis

8. Cellular Respiration8 What is photorespiration? “RUBP carboxylase/oxygenase” Why does it reduce PS carbohydrate yield? Under which conditions is it most problematic?

9. Cellular Respiration9 ‘C4’ photosynthesis How does it differ from C3? How does it address photorespiration? In which plants?

10. Cellular Respiration10 Why do some plants carry out ‘CAM’ photosynthesis? “Crassulacean Acid Metabolism” Which plants? Why is this beneficial? -- Water conservation
