Photosynthesis Question 30
30. Which of the following is not a product of light reaction of photosynthesis?
(a) ATP
(b) $NADH$
(c) Oxygen
(d) NADPH
Show Answer
Answer : b
Hints & Solution
(b) The light reactions of photosynthesis take place on the thylakoid membranes of the chloroplast. During light reactions of photosynthesis, light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP. ATP, NADPH and oxygen are products of light reaction, while NADH is a product of respiration process.
