Demonstrate the diverse scientific studies encompassing the chemical processes of living things. Essential life processes that may be understood using biochemical principles include cell signaling, energy and metabolism, and genetics. This set of three demonstrations teaches students about the biochemistry occurring in their own bodies. • pH and Protein Solubility—Examine the effect of pH on the solubility and structure of casein to find its optimum value. • Digestive Enzymes at Work—Learn how the body transforms the food we eat into essential nutrients needed to carry out cell processes and growth. • The Floating Catalyst—Investigate the reaction of catalase, which catalyzes the decomposition of hydrogen peroxide in plant and animal tissues.
Includes enough materials to perform each of the above demonstrations three times. This kit also comes with the Flinn ChemTopic™ Labs, Vol. 20, Biochemistry—The Molecules of Life, which contains instructions for four experiments and five demonstrations.
Concepts: Enzyme structure and function, proteins, pH. Time Required: One class period Materials Provided: Albumin, amylase, biuret test solution, casein, catalase, hydrochloric acid solution, hydrogen peroxide, iodine solution, pepsin, sodium hydroxide, starch, universal indicator solution, Flinn ChemTopic™ Labs, Volume 20, Beral-type pipets.
