The light-harvesting complexes of a chloroplast are located in the thylakoid membrane.
The enzymes of the calvin cycle reactions are located in the stroma.
Chloroplast, found in plant cells and some protists such as algae and cyanobacteria, is a cell organelle known as a plastid. Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane.
The enzymes required during the calvin cyle reaction are present in the stroma while, thylakoid System is the internal membrane system consisting of flattened sac-like membrane structures called thylakoids where light energy is converted into chemical energy. Thylakoids contain the light-harvesting complex, including the electron transport chains used in photosynthesis and pigments like chlorophyll and carotenoids.
