Question

Explain the process of photolysis of water ?

Answer 1

It is the process of break down of water into hydrogen and oxygen under the influence of light during the light reaction of photosynthesis

Answer 2

Answer:

• In this process, water breaks down into hydrogen and oxygen.
• It is called photolysis or photocatalytic splitting of water.
• It requires Z enzyme, light energy and electron carrier.
• The Z enzyme is also called oxygen evolving complex. It has four Mn ions.
• The light energy energizes the Man ions which removes the electrons from OH- component of water.
• This is how Oxygen is formed.
• The two other ions involved in this process are Ca2+ and Cl-.
