Inhibitor Memes

Classic competitive inhibition in action. The enzyme's trying to bind with its substrate, but the inhibitor molecule swoops in and blocks the reaction. Just like that awkward moment when you're about to talk to someone at a conference and a more charismatic researcher interrupts. The substrate's facial expression says it all - "I was literally just about to catalyze that reaction." Meanwhile, the enzyme is left with nothing but unfulfilled active sites and regret.
