Question

Result(s) of light reaction is/are

• A. Only $ATP$
• B. Only $NADPH+H^{+}$
• C. $ATP$ and $NADPH+H^{+}$
• D. Only $FAD$

Answer 1

Answer: (C)

During light reaction, energy from sunlight is absorbed and converted to chemical energy which is stored in $ATP$ and $NADPH+H^{+}$ . Proteins and pigments (chlorophyll and carotenoids) that function in the photochemical events of photosynthesis i.e., trapping the light energy and synthesis of $ATP$ and $NADPH+H^{+}$ , are embedded in the thylakoid membrane of chloroplast.
