BSCI105, Freshman Connection Fall 2010 Study Guide #18 I. Photosynthesis Vocabulary: Carbon cycle Chloroplast Stroma Thylakoid Grana Photosynthesis Photosystem Calvin cycle Light reaction Dark reaction NADP+ NADPH Chlorophyll Carotenoids Photophosphorylation Action spectrum Antenna complex Excitation Reaction center P680 P700 Photolysis Cyclic flow RuBP Rubisco Key Concept 1: Photosynthesis is a process that converts light energy into chemical energy through carbon fixation. Key Concept 2: Photosynthesis occurs in chloroplasts, double membrane organelles packed with internal (stromal) membrane disks (thylakoids) arranged in stacks (grana). Key Concept 3: Light energy is captured by photopigments in the thylakoid membranes and used to excite electrons that provide energy for electron transport chains that produce ATP and NADPH. Key Concept 4: The sum of wavelengths absorbed by photopigments in chloroplasts is the action spectrum, which is determined by the types and amounts of chlorophylls and carotenoids present. Key Concept 5: Chlorophyll a and b are the principle photosynthetic pigments of green plants,
