The document provides information about photosynthesis including: 1. Photosynthesis takes place in chloroplasts located in plant leaves. The light reactions occur in the thylakoid membranes and produce ATP and NADPH. 2. The Calvin cycle uses the products of the light reactions along with CO2 to produce G3P, which can then be converted into glucose and other organic molecules. 3. The two main stages, the light reactions and Calvin cycle, work together to ultimately convert sunlight, water and CO2 into oxygen and energy-rich organic compounds through the overall process of photosynthesis.
