Verified step by step guidance

Understand the role of each biomolecule in the body: Lipids are primarily used for long-term energy storage, nucleic acids are involved in genetic information storage and transfer, proteins serve structural, enzymatic, and functional roles, while carbohydrates are the body's primary source of quick energy.

Recall that carbohydrates are broken down into glucose, which is a simple sugar that can be rapidly metabolized to produce ATP (adenosine triphosphate), the energy currency of the cell.

Recognize that the process of carbohydrate metabolism begins with glycolysis, where glucose is converted into pyruvate, yielding ATP and NADH.

Note that carbohydrates are water-soluble and can be easily transported in the bloodstream, making them readily available for energy production compared to lipids, which require more complex processing.

Conclude that carbohydrates are the biomolecule primarily used by the body as a fast source of energy due to their efficient breakdown and rapid availability for cellular processes.
