Where does carbohydrate production occur in a thylakoid?

Carbohydrate production in a thylakoid occurs during the light-dependent reactions of photosynthesis. Specifically, the energy captured from sunlight is used to convert water and carbon dioxide into ATP and NADPH, which are then utilized in the Calvin cycle to synthesize carbohydrates. While the Calvin cycle itself occurs in the stroma of the chloroplast, the initial energy capture that supports carbohydrate production starts in the thylakoid membranes.
