Photosynthesis A great variety of living things on earth, including all photosynthetic microorganisms, synthesize their  foods from simple molecules such as carbon dioxide and water. In microorganisms, photosynthesis  occurs in unicellular algae and in photosynthesizing bacteria such as cyanobacteria and green and  purple sulfur bacteria. Photosynthesis  is actually two processes. In the first process, energy-rich electrons flow through a  series of coenzymes and other molecules, and this electron energy is trapped. During the trapping  process, ATP molecules and molecules of  nicotinamide adenine di-nucleotide phosphate  hydrogen (NADPH)  are formed, both rich in energy. These molecules are then used in the second  half of the process, where carbon dioxide molecules are bound into carbohydrates to form organic  substances such as glucose.  Photosynthesis occurs along the
