Enzyme Catalysis: How Do Enzymes Work? | AP Biology 3.2

This section of the AP Biology curriculum examines the mechanisms by which enzymes are able to catalyze biochemical reactions. We’ll start by taking a look at how reactions happen without enzymes, and why there is a certain amount of activation energy required before the reaction will take place. Then, we’ll see what happens in energetic terms to reactants as they go through a reaction catalyzed by an enzyme. To see how the enzyme actually lowers the required activation energy, we’ll take another look at enzyme structure and the process that occurs when a substrate binds to the active site of an enzyme. Lastly, we’ll look at how enzymes work in both endothermic and exothermic reactions! Resources related to this Video: ● Overview: The same information, for those who prefer to read.
