Which type of biomolecule serves as the primary source of energy for living organisms? A) Nucleic acids B) Proteins C) Carbohydrates D) Lipids

## Step 1<br />The question asks us to identify the type of biomolecule that serves as the primary source of energy for living organisms. The options provided are Nucleic acids, Proteins, Carbohydrates, and Lipids.<br /><br />## Step 2<br />Nucleic acids are primarily involved in the storage and transmission of genetic information, not energy production.<br /><br />## Step 3<br />Proteins are involved in virtually every function of an organism, but they are not the primary source of energy.<br /><br />## Step 4<br />Lipids, while they can provide energy, are primarily used for long-term energy storage, insulation, and cell membrane structure.<br /><br />## Step 5<br />Carbohydrates, on the other hand, are the body's main source of energy. They are easily and quickly converted into glucose, which is used by cells for energy.
