What are the chemicals used in the preparation of amino acids and proteins by archaebacteria?

Solution

Archaebacteria:
They are the members of the kingdom monera.
These are the most ancient bacteria found in the most extreme habitats such as salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens).
The structure of the cell wall is different from that of the other bacteria which helps them survive in extreme conditions.
The nucleotide sequences of its t-RNA and r-RNA are unique.
Chemical used:
The chemicals include ammonia (NH₃), hydrogen sulphide (H₂S), or methane (CH₄). Archaebacteria can prepare their own amino acids and proteins in presence of any one of the chemicals mentioned above.

Q. Assertion : Proteins are organic components.
Reason : Amino acids are the basic units of proteins formed by hydrolysis.

Enzymes are proteins. Proteins are long chains of amino acids linked to each other by peptide bonds. Amino acids have many functional groups in their structure.

These functional groups are many of them at least, ionisable. As they are weak acids and bases in chemical nature, this iohisation is influenced by pH of the solution. For many enzymes, activity is influenced by surrounding pH. This is depicted in the curve below, explain briefly.
