Photosynthesis ‒ Tree

Carbohydrates consumed in food originate in photosynthesizing organisms like plants. During photosynthesis, plants harness sunlight to transform carbon dioxide (CO₂) into sugar molecules such as glucose (C₆H₁₂O₆). This synthesis of glucose requires an energy input, as it involves creating a larger, energy-rich molecule. The process is described by the equation: 6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂ During photosynthesis, energy is supplied in the form of ATP (adenosine triphosphate), a high-energy molecule that serves as the primary energy currency for all cells. Much like currency is used to purchase goods, cells use ATP as energy currency to perform immediate work. The glucose produced by photosynthesis can be stored as starch in plants or glycogen in animals. These energy-storing polymers are later broken down into glucose, which is then used to generate ATP molecules. *LICENSES AND ATTRIBUTIONS CC licensed content, Shared previously, Energy and Metabolism, Authored by: OpenStax College.
