Light energy from the sun transforms six carbon dioxide molecules and six water molecules into one molecule of glucose (sugar) and six molecules of oxygen gas.
Products are substances formed as the result of a chemical reaction. Carbon dioxide and water are the reactants in photosynthesis and glucose and oxygen are the products.
Photosynthesis is responsible for absorbing atmospheric carbon dioxide and producing oxygen that is released into the atmosphere.
Photosynthesis creates an enormous biomass of carbohydrate (sugar) energy. Photosynthetic organisms create 176 billion tons of carbohydrates each year.
Early in Earth's history, photosynthetic organisms were responsible for oxygenating the atmosphere. According to "Science News," photosynthetic organisms may have begun to oxygenate the atmosphere as early as 3.46 billion years ago.
