Options

A. thylakoidlumen
B. photosystem-I
C. photosystem-II
D. stromal matrix

Answer

D

Explanation

The light-independent reactions (or dark reactions) take place in the stromal matrix of the chloroplasts. In light independent reactions, carbon dioxide is reduced to glucose (carbohydrate) by the hydrogen in NADPH by using the chemical energy stored in ATP. This reaction takes place in the presence of a substance called RuDP.
