Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is produced in photosynthesis from the photolysis of water.
A
H20
B
O
C
CO2
D
H
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -photolysis of water produces protons, electrons and oxygen.

Detailed explanation-3: -In this process of photolysis (“splitting by light”), H2O molecules are broken into hydrogen ions, electrons, and oxygen atoms.

Detailed explanation-4: -Sunlight catalyzes the splitting of water into separate hydrogen and oxygen atoms, in a process called photolysis. The oxygen is released as a waste product while the hydrogens build up to form a high concentration. These hydrogens run a series of reactions ending in two molecules: NADPH and ATP.

Detailed explanation-5: -This happens through the photolysis of water-light energy causes a water molecule to split apart and release hydrogen ions, electrons and oxygen.
