Answer the ff. questions:   1. To which class does each enzyme belong? Explain your answers.   a.) pyruvate decarboxylase   b.) alanine aminotransferase   c.) alcohol dehydrogenase   d.) hexokinase     2. Substrates and reactive groups in an enzyme’s active site must be precisely aligned in order for a productive reaction to occur. Why, then, is some conformational flexibility also a requirement for catalysis?   3. Some plants contain compounds that inhibit serine proteases. It has been hypothesized that these compounds protect the plant from proteolytic enzymes of insects and microorganisms that would damage the plant. Tofu, or bean curd, possesses these compounds. Manufacturers of tofu treat it to eliminate serine protease inhibitors. Why is this treatment necessary?
