Question

Which of the following is produced during the light phase of photosynthesis?

• A. $ATP$
• B. $NADPH_{2}$
• C. Both $ATP$ and $NADPH_{2}$
• D. Carbohydrates

Answer 1

Answer: (C)

Both $ATP$ and $NADPH_{2}$

Answer 2

Photochemical phase, also called light or Hill reaction, occurs inside the thylakoids, especially those of grana region. Photochemical step is dependent upon light. The function of this phase is to produce assimilatory power consisting of reduced coenzyme $NADPH$ and energy rich $ATP$ molecules.
