The study of the chemical processes within and relating to living organisms is known as biochemistry. This field explores the molecular mechanisms that underlie biological functions, including metabolism, enzyme activity, and the structure and function of DNA and proteins. By analyzing these processes, biochemists can understand how cells communicate, grow, and respond to their environments. Biochemistry plays a vital role in various disciplines, including medicine, agriculture, and environmental science, as it helps to uncover the biochemical changes associated with health and disease.
