Detailed explanation-1: -So, the correct answer is ‘NADH’.
Detailed explanation-2: -Thus, the end products of the photolysis reaction are oxygen, NADPH and ATP.
Detailed explanation-3: -In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). So NADH is not a product of the light reaction of photosynthesis.
Detailed explanation-4: -In this process of photolysis (“splitting by light”), H2O molecules are broken into hydrogen ions, electrons, and oxygen atoms.
Detailed explanation-5: -Water is an important raw material for photosynthesis. During the light reaction, light energy is utilized. By using light energy, water is split to form oxygen, and hydrogen and electron are released. This is known as the photolysis of water.
