Biological pathways are a series of chemical reactions that occur within living organisms to maintain life. These pathways involve various molecules, such as proteins, enzymes, and metabolites, working together to perform specific functions. For example, the glycolysis pathway breaks down glucose to produce energy, which is essential for cellular activities. Each biological pathway is tightly regulated to ensure that the right processes happen at the right time. Disruptions in these pathways can lead to diseases, such as diabetes or cancer. Understanding these pathways helps scientists develop targeted treatments and therapies to restore normal function in the body.
