Lecture Objectives Understand the reactions of photosynthesis. Know input and output of light reactions and Calvin cycle. Know where each occurs in prokaryotes and eukaryotes. Be able to trace the path of electrons as they move move through the Z scheme. Understand resonance and redox reactions and the difference between antenna pigments and the reaction centers Understand why a plant undergoes cyclic photo- phosphorylation and what is involved. Know the 3 phases of Calvin cycle Understand why rubisco is inefficient and the adaptations that C4 and CAM plants have made Understand the similarities between the mitochondria and the chloroplasts with respect to what is happening in each compartment
