Kemtec®. Students study the action and nature of enzymes as catalysts while performing 5 experiments. Using experimental controls and variables, students observe the action of amylase on starch, invertase on sucrose, and pepsin on protein. Students examine the rate of enzyme-catalyzed reactions and use changes in solution color and pH as indicators of chemical change. As an optional exercise, students can use a spectrophotometer to quantify their results. Materials are sufficient for 24 students working in 6 groups of 4.
Note: Kit includes reply card to request separate shipping of invertase, amylase, pepsin, and hemoglobin. These items cannot be shipped outside the continental United States. Please plan your lab accordingly. Perishables ship within two weeks after receipt of the perishables voucher.
