Photosynthesis Reaction, Light-dependent reactions and the Calvin cycle Learn Light and photosynthetic pigments Photosynthesis: Overview of the light-dependent reactions Conceptual overview of light dependent Light-dependent reactions are crucial because they are the first step in photosynthesis, converting light energy into chemical energy. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light. Photosynthesis is the fundamental process by which plants convert light energy into chemical energy, sustaining not only their own growth but also supporting life on Earth. This chemical energy, in the form of ATP and NADPH, fuels the subsequent light-independent reactions (Calvin cycle), which then produce sugar molecules. Photosynthesis can be broken into two stages: The light dependent reactions and the light independent reactions also known as the Calvin Cycle or dark reactions. Photosynthesis uses sunlight, carbon dioxide, and water to make glucose and oxygen in plants. Reactions of photosynthesis, where they take place, and their ecological importance.
