Question

During light reactions in photosynthesis the following are formed:

• A. ATP, hydrogen and
  $O_2$ donor
  
• B. $ATP$ and sugar
• C. ATP, hydrogen and $O_2$
• D. Hydrogen, $O_2$ and sugar

Answer 1

The correct option is C ATP, hydrogen and $O_2$

Light reaction :

• Light reaction in plants is the synthesis of chemical energy such as ATP and NADPH from the light energy of sunlight.
• It is a photochemical reaction and takes place in the thylakoid.
• It also involves the splitting of water to form $H^{+},O_2$ gas and electrons.
• Thus, the final products formed during the light reaction are ATP, NADPH, hydrogen, and $O_2$

Final answer :

C.ATP, hydrogen, and $O_2$
