Enzymes Specificity Enzymes and substrates bind at the active site Enzyme shape matches substrate shape Enzymes can be reused Enzymes and substrates bind at the active site Enzyme

Enzymes are like…

Enzymes & Chemical Reactions Enzyme names end in -ase. sucrase (enzyme) sucrose (substrate) Enzymes are not changed by the reaction. Substrates are changed digested synthesized

Examples of Enzymes substrate Active site

Examples of enzymes digestion reaction substrate active site enzyme enzyme unchanged

Enzymes in action Catalyze synthesis and digestion reactions Lewport Biology Place animation

Environmental Effects on Enzymes Temperature pH pH of 1-6 is an acid pH of 7 is neutral pH of 8-14 is a base Enzymes work best at an optimum temp & pH

Temperature Above the optimum temperature the enzyme denatures (changes shape). Activity 5.5 on PearsonSuccessnet
