Answer:
The answer is option B
Explanation:
The major organic molecules are considered as the building blocks for larger larger and more complex molecule that sustain life. These organic molecules are better known by the term "Biological Macromolecules".
Now, there are 4 categories of Biological macromolecules which are referred to as lipids, proteins, nucleic acids, and carbohydrates. The word organic is used to refer to the fact that his molecules contain the carbon element as is contained, indeed, by most molecules in any living entity.
Each macromolecule serves a vital function in a living cell. Proteins serve the point of quickening requisite chemical reactions and providing a structure to the cell. Lipids are involved in providing long term energy sources to the body by building up fat for example. Carbohydrates provide short-term energy as opposed to lipids for example in the form of cellulose. Nucleic acids are the conduits for genetic information and are contained in DNA fibers.
