Complexes of proteins and pigments that convert light energy to chemical energy. Converting light energy to chemical energy takes 4 steps. P680* transfers high-energy electron to 1^0 electron receptor. Ps ii is the only system that can oxidize water. Now, continue electron transport from psii to plastoquinone (pq) Pq to cytochrome complex ( c ) Cytochrome ( c ) to plastocyanin (pc) Pc not membrane associated - chills out in the thylakoid lumen. Ps1 receives a love energy electron from pc. Complex of pigments that can interact with light. Electron is transferred to ferredoxin (fd) - iron. Fd works with nadp reductase (=n) to produce nadph in stroma. Atp synthase uses the proton gradient to produce atp in stroma. Linear or noncyclic electron flow between water and nadp+ Use atp and nadph to reduce co2 and thus make carbs. Incorporating inorganic carbon into an organic molecule. Need 18 atp and 12 nadph for every 6 co2 incorporated.

Photosynthesis is the process by which plants convert theradiant energy from the sun to chemical energy. The rate in whichphotosynthesis occurs is dependent upon three main variables:light, Carbon dioxide (CO2) concentrations, and temperature. Howwould the process of photosynthesis be affected, and in what steps,if light, CO2 concentration, and/or temperature were altered duringphotosynthesis?
