Question

Following table summarises the differences between light reaction and dark reaction.

	Light reaction	Dark reaction
i	These are also called as biosynthetic phase	These are also called as photochemical phase
ii	These reaction occur over thylakoids.	These reaction occur in stroma of chloroplasts.
iii	These produce assimilatory power i.e.$NADP{H}_2$and ATP	These consume $NADP{H}_2$ and ATP.
iv	These are direction dependent upon light.	These depend upon the products synthesised during light reaction

Which of the above pairs of difference is/are incorrect?

• A. (i) and (iv)
• B. (iii) and (iv)
• C. (ii) only
• D. (i) only

Answer 1

Answer: (D)

(i) only

The light reaction is also called as photochemical phase whereas dark reaction is called as biosynthetic phase.
