Question

Light reaction in stroma lamellae of chloroplast results in the production of

• A. ATP
• B. NADPH${}_2$
• C. ATP + NADPH${}_2$
• D. O${}_2$

Answer 1

Answer: (C)

ATP + NADPH${}_2$

A) Along with ATP, ${NADPH}_2$ is also produced.
B) Along with ${NADPH}_2$, ATP is also produced.

C) The light reaction that takes place in the stroma lamellae is the non-cyclic phosphorylation and ATP and ${NADPH}_2$ are the products.
D) Oxygen is also liberated during the light reaction but is not the main product.
So the correct answer is 'ATP + ${NADPH}_2$'.
