RuBisCO is essential for carbon fixation in C3, C4 and CAM plants. < >. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions. Using the energy carriers formed in the first stage of photosynthesis, the Calvin cycle reactions fix CO 2 from the environment to build carbohydrate molecules. It is present in the bundle sheath cells where it takes part in the Calvin cycle. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Under saturating light conditions at low levels of intercellular CO2, assimilation is limited by the quantity and activity of rubisco, the enzyme that is primarily responsible for capturing atmospheric carbon in the production of sugars.
