- AsapIn photosynthesis, contrast the light reactions with the light independent reactions, in terms of goals, inputs, and outputs of each. Spatially where do they take place (which parts of the chloroplast)? (Optional, for further discussion: Could there be light reactions without light-independent reactions, or visa-versa?)Describe the purpose of the light dependent reaction and light independent reaction (carbon fixation reaction) in photosynthesis. In addition, explain how the products of the light dependent reaction are used in the light independent reaction (carbon fixation reaction)
