Answer:

The <u>stroma</u> within the chloroplast

<u />

Explanation:

Chloroplasts are membrane-bound organelles  in plants. They comprise many invaginations of a plasma membrane called a thykaloid membrane. This includes chlorophyll pigments in layers called granum, whereas the internal spaces of the organelle are called lumens. Fluid surrounds the granum, and forms the stroma; here, all metabolic reactions within the chloroplast occur- <u>including CO2 fixation.</u>

Photosynthesis, involves the conversion of energy from photons or light particles and water, starting in the thykaloids; here, the pigments like chlorophyll, which is essential to photosynthesis, reside.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen
