Photosynthesis outline How do living organisms capture light energy? What reactions convert light energy to chemical energy? How did the complex, modern oxygenic photosynthesis evolve? What reactions reduce carbon dioxide to carbohydrate? How will increasing carbon dioxide in the atmosphere affect photosynthesis?

Photosynthesis themes Light energy is used to generate a proton gradient across a membrane for chemiosmotic ATP synthesis. Light energy is used to reduce electron carriers that are used, in turn, to reduce inorganic carbon (CO 2 ) to make carbohydrate (CH 2 O). A key innovation enabled cyanobacteria to take electrons from water molecules instead of organic molecules or sulfur and changed the surface of the planet forever. Photosynthesis reverses electron flow of respiration
