Hint: Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. In photosynthesis as a result of this, oxygen and hydrogen is released.
Complete Answer:
A) Carbohydrate is an organic molecule that contains carbon, hydrogen and oxygen. Hydrolysis of carbohydrates occurs and as a result it is broken down into many sugar components such as glucose, fructose. Sucrose is broken into sugar molecule glucose. This process is known as saccharification.
B) The process of breakdown of proteins is called protein catabolism. As a result, several amino acids and other derivatives are formed. Several protease enzymes that are non-specific are the result of protein catabolism. These protease enzymes responsible for protein cleaving or protein trafficking. Oligopeptidase is an example of proteolytic enzymes.
C) Reduction of carbon dioxide which is also an photoelectrochemical process is involved in the reduction of carbon dioxide into carbon monoxide and several other derivatives. Sometimes many hydrocarbons are produced by the effect of incident light. The species which are reduced are sometimes proved to be effective for feedstock or several other processes.
D) Hydrolysis of water is the most important part in photosynthetic processes. In the case of hydrolysis, water molecules are broken down in presence of some conditions. It is a chemical process that occurs so fast. In this case water is broken down into hydrogen and hydroxyl ions. From these hydrogen ions, hydrogen is derived further.
Hence Option D: Hydrolysis of water is the correct answer.
Note: The associated hydrogen ions are released from the water molecule, and after two water molecules are thus split, the oxygen atoms join to form molecular oxygen ( ), a waste product of photosynthesis.
