Document Summary

Photosynthesis: the process by which light is converted to chemical energy (stored in sugar and other molecules) Source of oxygen and reduced carbon for all other forms of life (basis of life for higher trophic levels) plants are primary! 6co2 + 6h2o c6h12o6 + 6o2. Plants also have mitochondria so they perform cellular. Green bc of chlorophyll molecules in the thylakoid membrane. Violet-blue/ red wavelengths work the best of photosynthesis. Hydrocarbon tail- interacts with hydrophobic regions of proteins inside thylakoid membranes of chloroplasts. Light particle is absorbed by chlorophyll (photosystem ii) and excites an electron. It shoots up and travels down the electron transport chain. Water is broke up into o2 and 2h+ to replace the electron that left. (photophosphorylation) as electrons move down the electron transport chain, h+ is pumped into the thylakoid space through the atp synthase (creating high h+ concentration) and diffuses back into the stroma creating atp.
