Answer:
Generally the primary organic molecules in cells which support the metabolic and biochemical process of the cells are bio molecules Theses are Carbohydrate
Protein
Lipids
and Nucleic acids of DNA and RNA. They can also be the minute hormones and metabolites present in the cells.
Generally, CHO provide structural supports to the cells,and acts as sources of energy.
Protein forms most enzymes for biochemical reactions,and aids movements, through muscle contractions. Besides,muscles are made of protein.Therefore protein forms the structural basis of the muscles.This aids movement and locomotion for support.
Lipids are the richest source of energy for the cell,and provides support the cells membrane.
The nucleic acids,are primary concerned with the transfer of inheritable characteristic from mother cells to the daughters during reproduction.While the DNA is the genetic information been transferred,the RNA is the vehicle for transmission of the genetic information as protein from the parents' nucleus to the offspring. Thus the nucleic acid roles it for transmission of genetic information as genes,(DNA) and translation of these genes as proteins(RNA).Hence,Nucleic acids does not participate in the cells' support.
Therefore
