Here's why:
* Stroma: The stroma is the fluid-filled space within the chloroplast, surrounding the thylakoid membranes. It contains enzymes, ribosomes, and DNA, making it the site of many metabolic reactions.
* Thylakoid membranes: These are the sites of the light-dependent reactions, where light energy is captured and used to produce ATP and NADPH.
* Calvin cycle: This cycle uses the energy from ATP and NADPH generated in the light-dependent reactions to convert carbon dioxide into glucose. The enzymes and molecules necessary for the Calvin cycle are located in the stroma.
Therefore, the stroma is the key location for the light-independent reactions of photosynthesis.
