Question

Find out the incorrect statement from the following.

• A. Dark reaction depends on the product formed by light reaction.
• B. In stroma, enzymatic reactions incorporates $CO_{2}$ into the plant leading to the synthesis of sugar.
• C. Purple and green sulphur bacteria use $H_2 S$ as hydrogen donor.
• D. There is no division of labour in chloroplast.

Answer 1

Answer: (D)

Division of labour occurs in the chloroplast. In grana, light reaction occurs in which ATP and NADPH + H are synthesized, which are used in dark reaction to reduce carbon dioxide to glucose. All enzymes of the Calvin cycle are present in the stroma.
