What is your prediction for this experiment? A. A reaction will take place if water is present. B. Any combination of chemicals that contains an enzyme will exhibit a reaction. C. Only specific combinations of an enzyme and substrate will exhibit a reaction.

In the world of biochemistry, enzymes are like the VIP guests at a party—they're very selective about whom they interact with! Enzymes typically work on specific substrates, meaning they have unique shapes that only fit certain molecules. This specificity is often described by the "lock and key" model, making option C the star of the show when it comes to predicting the outcome of your experiment. It's fascinating to consider that this principle has real-world applications beyond the lab! For instance, in the field of medicine, enzyme inhibitors can be developed as medications to target specific pathways in diseases. Similarly, in the food industry, enzymes play a crucial role in processes like brewing and cheese-making, showcasing just how vital these selective interactions are in our everyday lives.
