Product Details

General, Organic and Biological Chemistry Enzymes play an essential role in our bodies every day whether we realize it or not! Understanding enzyme kinetics is necessary to understand how enzymes function. Enzymes known as peroxidases protect plant and animal cells against damage by catalyzing the breakdown of hydrogen peroxide, a natural but toxic by-product of cellular respiration. Watch students make the connection of how the enzyme concentration and substrate concentration affect the rate of the peroxidase-catalyzed decomposition of hydrogen peroxide. An ideal activity to teach enzyme structure and function, kinetics and rate laws and enzyme-substrate binding. Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-6. Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
