Anabolic pathways are a series of biochemical reactions that build complex molecules from simpler ones. These pathways require energy, often derived from the breakdown of ATP (adenosine triphosphate). Anabolic processes are essential for growth, repair, and maintenance of cells and tissues in living organisms. Common examples of anabolic pathways include the synthesis of proteins from amino acids and the formation of glycogen from glucose. These processes are crucial for storing energy and creating the structural components necessary for cellular function and overall organismal health.
