The study of chemical processes in living organisms is referred to as biochemistry. This field focuses on understanding the molecular mechanisms that underlie biological functions, including metabolism, enzyme activity, and genetic processes. Biochemists investigate the roles of biomolecules such as proteins, carbohydrates, lipids, and nucleic acids in cellular processes. Understanding these chemical interactions is essential for advancements in fields like medicine, agriculture, and environmental science, as it helps address various biological challenges and disease mechanisms.
