In photosynthesis, the light independent reactions takes place at:
|
|
Photosystem-II
|
|
|
Stromal matrix
|
|
|
Thylakoid lumen
|
|
|
Photosystem-I
|
Explanation:
Detailed explanation-1: -In photosynthesis, light independent reactions are known as dark reactions. They take place in the stromal matrix of chloroplast where all the enzymes required for the reaction are present.
Detailed explanation-2: -The light-dependent reactions occur in the thylakoid membranes of chloroplasts, whereas the Calvin cycle occurs in the stroma of chloroplasts. Embedded in the thylakoid membranes are two photosystems (PS I and PS II), which are complexes of pigments that capture solar energy.
Detailed explanation-3: -The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.
