#8: Use of Chemicals in Defined Growth Medium: The following chemicals commonly found in defined growth media contain all of the necessary atomic macronutrients, namely C, O, N, S and P,which microbes require: glucose (Cat O), KH PO MgSO, 7H,0, and (NHa)HPO. Create a simple diagram to map which growth media chemical contributes atoms to the chemical makeup of the four biological macromolecules (amino acids polysaccharides, lipids, and ribonucleic acids. Your diagram could show the macronutrient compounds in a column on the left hand side of the page, the cellular macromolecules on the right hand side of the page, and then arrows between certain compounds and macromolecules to answer the question.Explanation / Answer
Glucose (C6H12O6) -------> 1. Helps in polyspolysachharide formformation 2. Helps in formation of amino acid via pentose phosphate pathway ( erythorse 4 phosphate to tryptophan , phosphoneol pyruvate to tyrosine) 3. Lipid biosynthesis 4. Sugar backbone of RNA ( ribose sugar via pentose phosphate pathway and Entner - duodroff pathway)
KH2PO4 - acts as a phosphate source , Helps in synthesis of phphospho di ester bonds in RNA or DNA , Pottassium acts as several co-factor for various enzymes.
MgSO4 , 7 H2O ------> Mg is an useful ion for replication enzymes , S is essential for formation of sulphides bonds iin protein ,
( NH 4)HPO4 ----------> acts as a nitrogen source helps in amino acid biosynthesis and nucleic acid biosynthesis.
