Activation Energy:Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that must be overcome before a reaction can proceed.
Denaturation:Denaturation occurs when high temperatures or extreme pH levels cause an enzyme to lose its shape and function. It's like a chef who becomes so overwhelmed with heat that they forget how to cook properly.
Substrate:Substrate refers to the specific molecule on which an enzyme acts. In our analogy, it's like the ingredients that the chef uses to create a dish.
