The enzymes for the biosynthetic reactions or the carbon assimilation are found in the
-
stroma of chloroplast
-
stomata of leaf
-
grana of chloroplast
-
mitochondrial matrix
A
Correct answer
Explanation
The Calvin cycle enzymes are located in the stroma of chloroplasts. This is where carbon fixation and carbohydrate synthesis occur during the dark reactions of photosynthesis. Grana contain chlorophyll for light reactions, while stomata are pores for gas exchange and mitochondria handle cellular respiration.
