Photosynthesis Photosynthesis is the process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the basic energy source for just about all organisms. Oxygen, which is a necessity of life for just about every organism, is a byproduct of photosynthesis. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms produce millions of new glucose molecules …

…new molecule of glucose has been constructed and five molecules of RuBP have been reconstructed. This process occurs repeatedly in each chloroplast as long as carbon dioxide, ATP, and NADPH are available. The thousands of glucose molecules produced in this reaction are processed by the plant to produce energy in the process known as aerobic respiration, used as structural materials, or stored. The regenerated RuBP is used to start the Calvin cycle all over again.
