The oxygen released during photosynthesis process comes from

A. H2O

B. CO2

C. NO2

D. Glucose

Answer: Option A

Solution(By Examveda Team)

During the process of photosynthesis, green plants and some other organisms use sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose (a type of sugar) and oxygen (O2). This process takes place in the chloroplasts of plant cells and is represented by the following chemical equation:

6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

As you can see, the oxygen released during photosynthesis comes from the water molecule (H2O). Carbon dioxide (CO2) is used to produce glucose (C6H12O6), which serves as an energy source for the plant. So, the correct answer is Option A: H2O.

    It from water due to the process photolysis of water
    2H2O>>>>2H+ + 2OH–
