Final answer:
The enzymes that synthesize carbohydrates are located in the stroma of the chloroplast.
Step-by-step explanation:
The enzymes that synthesize carbohydrates are located in the stroma of the chloroplast, which is the fluid-filled space inside the inner membrane surrounding the thylakoid stacks called grana.
Chloroplasts are organelles found in plant cells where photosynthesis takes place. The grana consist of sac-like membranes called thylakoid membranes, which contain the enzymes responsible for the light reactions of photosynthesis. The stroma, on the other hand, is where the reactions of the Calvin cycle occur, including the synthesis of carbohydrates.
