Document Summary

Plants can convet light energy into chemical bond e. Chloroplasts conversion of light e into chemical bond e(simple sugar) eukaryotes: structure(3 membrane system) Use spectrophotometer to measure light intensity: absorption spectrum - absorption of light of different wavelengths, action spectrum determines which wavelengths are most efficient for photosynthesis. 6. reaction center specialized cholorophyll a molecules are capable of transferring e- to primary electron acceptors. Psi absorption best at 700nm called p700(type of chlorphyl a) Oxygen released = this process is photolysis. Missing electron replaces by the one that travelled down psii. Non cyclic electron transport z-scheme: as e- move down etc in psii+psi pumps h+ across thylakoid membrane. Electron passes down etc until goes back to p700+ Cyclic: e pumps protons into thylakoid lumen important in producing atp, summary of cyclic p700-- e- cycled, protons pumped, atp eventually produced, no nadph.
