By investigating biomolecules such as proteins, nucleic acids, carbohydrates, and lipids, biochemists elucidate how these molecules interact and contribute to life as we know it.

One of the foundational elements of biochemistry is the study of metabolism, which encompasses all chemical reactions that maintain the living state of cells. Metabolism can be categorized into two distinct pathways:

• Anabolism: The metabolic pathway that builds complex molecules from simpler ones, requiring energy input. This process includes the synthesis of proteins from amino acids and the formation of DNA from nucleotides.
• Catabolism: The process of breaking down complex molecules into simpler ones, releasing energy. This pathway involves cellular respiration, where glucose is oxidized to produce ATP (adenosine triphosphate), the energy currency of cells.
