Biochemical processes are the chemical reactions that occur within living organisms, enabling them to grow, reproduce, and respond to their environment. These processes involve biomolecules such as proteins, lipids, carbohydrates, and nucleic acids, which play crucial roles in cellular functions. For example, cellular respiration converts glucose into energy, while photosynthesis allows plants to convert sunlight into chemical energy. These processes are essential for maintaining life and are regulated by enzymes, which are proteins that speed up chemical reactions. Understanding biochemical processes is fundamental in fields like biochemistry, molecular biology, and medicine, as they help explain how organisms function and how diseases can affect these vital reactions.
