How Do Enzymes Drive Chemical Reactions In Cells? Have you ever wondered how chemical reactions occur so efficiently inside living cells? In this informative video, we'll explain the essential role that enzymes play in biological processes. We'll start by defining what enzymes are and how they act as biological catalysts to speed up reactions. You'll learn how enzymes lower the activation energy needed for reactions to proceed, making vital cellular functions possible at normal body temperatures and pH levels. We’ll discuss the structure of enzymes, focusing on the active site where substrates bind and how the induced fit model helps facilitate reactions. The video will also cover the various mechanisms enzymes use, such as bringing molecules together in the correct orientation, weakening bonds, and stabilizing transition states. Additionally, we'll explore how enzymes do not alter the overall energy change of a reaction but instead make it easier and faster for reactions to reach completion. The importance of enzyme regulation within cells will be explained, including factors like temperature, pH, inhibitors, and feedback mechanisms. Understanding how enzymes work is fundamental to grasping how cells produce energy, synthesize molecules, and maintain life.
