Essay --

ationship of the Structure 0f Biomolecules to their Functions in Living Organisms Living organisms are highly ordered and have the ability to grow, develop and reproduce, complex organisms including humans rely on cooperation between organs, tissues, cells and molecules to exist (Bailey, 2014). Complex living organisms such as mammals are made of up cells, which develop into tissues, organs and finally the organ systems. All living organisms are made up of cells, organisms can be unicellular or multicellular. The cell is the fundamental unit of structure and function of all living organisms, it is the foundation on which living organisms are erected. There are two main type of cells; the prokaryotic cell and the eukaryotic cell. The prokaryotic cell lacks a true nucleus while the eukaryotic cell has a true nucleus. The cell consists of a protoplasm bounded by a membrane which comprises of four main biomolecules which are; carbohydrates, p roteins, lipids and nucleic acids. Each of these biomolecules has its own group of smaller molecules classified under them whose structures also take part in chemical reaction. Carbohydrates are the primary sources of energy to the cell, lipids provide structural support to the cell membrane, proteins functions mainly as enzymes and the nucleic acids stores and carriers genetic information. This essay will discuss how the structure of molecules can enable them to function in different organisations of life. Monosaccharide are single molecules sugar that form the basic units of carbohydr... ...the recipe to the ribosome in the cytoplasm. In the translation stage, the mRNA is decoded to produce a definite amino acid chain or a polypeptide which will then form into an active protein. Each codon codes for a specific amino acid, the structure of codons allow different amino acids to be coded for because of their diverse sequences that they can be establish. To sum up, all biological molecules play very important roles both at the cell level and system level in organisms. However, some of these molecules are more important than the other in the sense that they can take part in almost all the metabolic reactions in living organisms at all levels of life. For example, proteins take part in most metabolic and anabolic reactions in organism, it also takes part in protein synthesis which involves nucleic acids and they are also present in the phospholipid bilayer.
