What is the relationship between structure and function of biological molecules?
Llana [10]

Biological molecules or biomolecules are the carbohydrates, proteins, lipids and nucleic acids that are produced by the living organism. A very significant relationship lies between their structure and function as they are inter relatable.

Biomolecules are designed in such a way that on forming a particular structure only their specific functions can be formed. It is to ensure that no molecules other than the desired ones bring a change. If the latter situation arises, it may refer to harm or lethality.

For instance, insulin binds to its receptor and decreases the blood glucose level. Change in its structure will lead in inability to bind to the receptor specifically designed to accomodate it. And if function is not dependent on structure, then any molecule may bind to the receptor and decrease the blood sugar level to the point that body may not be able to function.
