Document Summary
Energy from light is converted to chemical energy (sugars) Co2 + h2o sugars + o2. Stroma: interior of chloroplast (cytoplasm of original cyanobacterium) Proteins involved in photosynthesis are mostly in the thylakoid membrane and stroma. Light-dependent reactions: production of atp and nadph for use in calvin cycle. Light-independent reactions (calvin cycle): production of glucose from co2 using atp and. This would be referred to the calvin cycle. Light-dependent reactions: converting energy from sunlight to chemical energy in the form of nadph and atp: light harvesting getting the energy, electron transport - reduction, photophosphorylation formation of atp. Sunlight + adp + nadp+ + h2o atp + nadph + o2. Antennae (light-harvesting complex): chlorophylls and other pigments that absorb energy from light and transmit the energy to reaction centers. Reaction center: unique chlorophyll-protein complex that transduces the energy from antennae to electron transport. Photosystem: complex containing the antennae, reactions centers, and other proteins involved in photosynthesis.
