Carbon dioxide, water, and sunlight can make oxygen and glucose {photosynthesis}|.
process
First, light reacts with water, NADP+, and ADP to make oxygen, NADPH, H+, and ATP {light phase}. Light oxidizes pigments, to release electron. Donated electron adds to NADP+. Electron transport chain and oxidative phosphorylation make ATP and oxygen. Then carbon dioxide, NADPH, H+, and ATP make glucose, NADP+, and ADP {dark phase}, with no light required.
pigments
Chlorophyll a absorbs orange light, and chlorophyll b absorbs red light, making plant green. Yellow, red, or purple carotenoid pigments absorb at different wavelengths. Xanthophyll carotenoid absorbs yellow. Physobilin carotenoid absorbs blue or red.
Older system absorbs light at 710 nanometers and makes ATP but no oxygen. Newer system absorbs light at 680 nanometers and makes oxygen.
bacteria
Nitrogen-fixing bacteria use photosynthesis to make nitrogen into ammonia. Nitrate-fixing bacteria use photosynthesis to make ammonia. Sulfur bacteria use photosynthesis to make sulfates.
