Competitive Inhibitors
Definition
These are molecules that bind to the active site of an enzyme, preventing the substrate from binding and thus inhibiting the enzyme's function.
Analogy
Imagine you're at a concert and you have a VIP pass (you're the substrate) that allows you to meet your favorite band backstage (the enzyme). But just as you're about to enter, someone else with a fake VIP pass (competitive inhibitor) rushes in and takes your spot. You can't meet the band because this imposter took your place!
