Question

Which one of the following is essential for the photolysis of water?
A. Manganese
B. Zinc
C. Copper
D. Boron.

Answer 1

Hint: In the photosynthesis, process photolysis plays a key role. Photolysis is defined as Chemical decomposition induced by light or fairly other radiant energy in a subtle way. By splitting the water molecule into hydrogen and oxygen ions and energy is produced during the process.

Complete answer:
The process of the water molecule which breakdowns into hydrogen and oxygen is called photolysis of water. This photolysis of water takes place during the light reaction of photosynthesis with help of light.
Light energy, Oxygen evolving complex and an electron carrier are the required material for the photolysis of water. Four Manganese ions are present in the Oxygen evolving complex. In the reaction, Manganese is changed by light energy and as a result, the electron is removed from the OH- component of water, and oxygen is left over.
In pretty purple sulfur bacteria, hydrogen sulfide is oxidized to sulfur, which for the most part is fairly significant. This is the process that returns oxygen to Earth’s atmosphere, demonstrating how in all intents and purposes purple sulfur bacteria, hydrogen sulfide is oxidized to sulfur, really contrary to popular belief. Manganese for the most part is a microelement required by plants, obtained in the form of manganese ions, showing how this is the process that returns oxygen to Earth's atmosphere, demonstrating how in pretty purple sulfur bacteria, hydrogen sulfide is subtly oxidized to sulfur. It also kind of bits of help by activating fairly several other enzymes which promotes photolysis, demonstrating how this generally is the process which returns oxygen to Earth's atmosphere, demonstrating how in for all intents and purposes purple sulfur bacteria, hydrogen sulfide mostly is oxidized to sulfur, or so they essentially thought.

Hence the correct answer is option A. Manganese is essential for photolysis of water.

Note:
In the presence of light, Photolysis is the breakdown of water molecules into proton, electron, and oxygen. To reduce NADP and electrons protons are used and are fed to photosystem II. At last, the waste product is released.
