The part of an enzyme where substrate molecules bind and undergo a chemical reaction. It’s like the profile page on your dating app – it’s where all interaction happens!
Lock-and-Key Model: A model suggesting that enzymes and substrates fit together perfectly due to their complementary shapes, just like puzzle pieces or keys fitting into locks.
Induced Fit Model: An updated model suggesting that enzymes change shape slightly when they bind with their substrates, much like hugging someone tightly.
