Product Details

General, Organic and Biological Chemistry Organisms that do not make their own food must break down large molecules to generate the “building blocks of life.” Investigate the properties of digestive enzymes that break down plant and animal tissue—food—into glucose, amino acids and fatty acids needed for metabolism and growth. Students will investigate the actions of amylase, pepsin and lipase on proteins, starches and fats in a series of chemical tests. The results are used to determine the optimum pH conditions for specific enzymes. Complete for 24 students working in pairs for Part A and groups of 4 in Part B.

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.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
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.
