Specificity: Enzymes catclyse only a few reactions due to the precise tertiary shape so only certain substrates fit into the active site
Active site: Cleft where substrate binds and reaction takes place.Complimentary to substrate
Lock and Key hypothesis: Proposed by Fischer. Only a single substrate fits into an active site
Induced fit hypothesis: Proposed by Koshland. Active site moulds to substrate as it enters. Bonds form between substrate and R-group to induce a better fit
Eenzyme Substrate/Product complex: In catabolic reaction, strains increase likelihood of breakage. In anabolic reaction, substrates are brought closer together. The enzyme is released unchanged
Lowering of activation energy: Enzymes increase likelyhood of reaction by lowering activation energy so more substrates can react that wouldnt have before
