EnzymesMighty powerhouse peptidesCause reactions to go fasterIn the cell’s insides

Tiny substratesBring about an induced fitEnzyme structure is affect-edBy what binds to it

Can it be that it’s just simple zen?How the enzymes activateIf they bind effector, will they goTo an R-State, T-State?

FoldingGives the mechanistic mightTo three-D arrangementOf the active site

EnzymesHave a bias they can’t hideHydrophobic side chains areMostly found inside

So it’s the structureFor celebratingWhenever there’s debatingThe way they workThe way they work
