Question

Stroma in the chloroplast of higher plant contains:

• A. Chlorophyll
• B. Light-independent reaction enzymes
• C. Light-dependent reaction enzymes
• D. Ribosomes

Answer 1

The correct option is B Light-independent reaction enzymes

Photosynthesis occurs in two phases - The light-dependent reaction and the Light-independent reaction. The light-dependent reaction is catalyzed in the grana of the chloroplast, leading to the formation of the assimilatory molecules of ATP and NADPH. These are then used in the Light-independent reaction, also called the dark reaction in the stroma of the chloroplast. The enzymes for the dark reaction are present in the stroma of the chloroplasts.

Hence, the correct answer is 'Light-independent reaction enzymes'.
