Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
This new model may better explain the elements required for photosynthesis to occur. Sunlight, water, and carbon dioxide are required for the plant to produce its own food. Someone who is unfamiliar with the process of photosynthesis must begin with the basics and then build on this knowledge.
