Lecture 2: Science of Enzymes Lesson 2 1. Enzymes defined- protein catalysts that accelerate specific chemical reactions a. As catalysts enzymes: i. Speed reactions ii. Participate in reactions but are not consumed or changed and are highly specific 2. Enzyme Animation a. Each enzyme has only one reaction that it can help i. Enzymes are not changed and can there for be used over and over again b. Some enzymes may even be used repeatedly on the same set of small molecules to build a long chan of repeating subunits c. As with all prteins the shape of an enzyme is what determines its function. An orgainism has the ability to make many different enzymes and each enyme has one particular funtion. d. Sometimes, high temperatures or extream pH values may affect the shape of an enzyme molecule. i. Denaturing- makes the enzymes less effective, possibly even useless 3. Enzymes as catalysts a. Lowers the amount of energy needed 4. Enzymes as proteins a. Shape is key to function. The active site lend specificit to the reaction
