Biological pathways are series of chemical reactions occurring within a cell that lead to specific outcomes, such as energy production or the synthesis of important molecules. These pathways involve various molecules, including enzymes, substrates, and products, which interact in a regulated manner to ensure proper cellular function. One well-known example of a biological pathway is the glycolysis pathway, where glucose is broken down to produce energy in the form of ATP. Understanding these pathways is crucial for fields like biochemistry and medicine, as they help explain how cells respond to different stimuli and maintain homeostasis.
