A biological process refers to any series of actions or changes that occur within living organisms. These processes are essential for maintaining life and include functions such as metabolism, cell division, and photosynthesis. Each process is driven by complex interactions between various biological molecules, including proteins, nucleic acids, and enzymes. Biological processes can be categorized into two main types: anabolic and catabolic. Anabolic processes build complex molecules from simpler ones, while catabolic processes break down complex molecules into simpler forms. Together, these processes enable organisms to grow, reproduce, and respond to their environment, ensuring their survival and adaptation.
