Answer:
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Step-by-step explanation:
Biological molecules (bio-molecules) are the building blocks of a the cell.
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Proteins are large biological molecules composed of smaller molecules called amino acids. Proteins are required for many important functions in the cell such as cell structure, metabolism and growth.
Nucleic acids are important biological molecules that contain the information required for the continuity of life.
Carbohydrates are essentially required for nutrition and growth. They also serve structural purposes as well as many other functions.
Lipids are divided into fats and oils. They serve various functions such as energy stores, and also provide insulation to the living organism.
