Calvin Cycle

Calvin Cycle

The Calvin cycle is a called the “light-independent reaction” part of photosynthesis because it does not utilize light photons to produce a product. It is also a redox reaction. The goal of the Calvin cycle is to convert carbon dioxide and water into organic compounds. The Calvin cycle occurs in the stroma of chloroplast organelles. Through a complex process of interactions and reactions, the Calvin cycle converts 3 C02, 6 NADPH, 5 H2O, and 9 ATP into G3P, 2 H+, 6 NADP+, 9 ADP, and 8 phosphates per cycle. The enzyme RuBisCO is the key component in this process. Without the Calvin cycle, photosynthesis would be impossible. The leaf pictured in the image above is currently undergoing photosynthesis (and thus the Calvin cycle).
