Enzyme Catalysis Mechanisms
This quiz covers the mechanisms of enzyme catalysis, including the lock-and-key model, induced-fit model, and conformational-selection model, and explores the strategies of covalent catalysis, general acid-base catalysis, catalysis by approximation, and metal ion catalysis.

- Card 1HintThink about forming a temporary chemical link.Memory TipCovalent: shared bond with substrate.
- Card 2HintConsider the act of giving or taking protons, but not just by water.Memory TipAcid-Base: proton transfer by non-water.
- Card 3HintImagine two distinct partners coming close to collaborate.Memory TipApproximation: two substrates meet.
- Card 4HintConsider a metallic element facilitating the reaction.Memory TipMetal: helps attacking nucleophile.
- Card 5HintThink of an 'indirect' way to control enzyme function.Memory TipAllosteric: indirect enzyme control.
- Card 6HintImagine the enzyme is 'tight' or 'unwilling' to bind.Memory TipT-state: Tense, less affinity.
- Card 7HintPicture the enzyme being 'open' or 'ready' to bind.Memory TipR-state: Relaxed, ready to bind.
- Card 8HintThink of a 'unified' or 'everyone at once' change.Memory TipConcerted: all change together.
- Card 9HintConsider a 'step-by-step' or 'one after another' influence.Memory TipSequential: one by one influence.
- Card 10HintThink combining 'oxidation' and 'reduction'.Memory TipOxidoreductases: redox reactions.
- Card 11HintConsider moving a part from one place to another.Memory TipTransferases: moves chemical groups.
- Card 12HintRemember 'hydro' for water and 'lysis' for breaking.Memory TipHydrolases: breaks bonds with water.
- Card 13HintThink of 'cutting' bonds without water or redox.Memory TipLyases: breaks bonds directly.
- Card 14HintConsider changing the 'shape' or 'arrangement' of a molecule.Memory TipIsomerases: same atoms, different form.
- Card 15HintThink of 'ligating' or 'tying together' two things.Memory TipLigases: glues two molecules.
- Card 16HintImagine a perfect, pre-existing fit between two objects.Memory TipLock & Key: perfect fit.
- Card 17HintIt's the specific area where the action happens.Memory TipActive site: reaction center.
