Grades 9–12.
- Model the formation of starches, glycogen, cellulose, lipids, and proteins
- Investigate how an enzyme decomposes hydrogen peroxide
- Design an experiment and interpret data
Students use molecular models to discover that macromolecules are found in all living organisms. They then investigate how specialized proteins known as enzymes can act as catalysts to speed up chemical reactions within organisms. In the final activity, students design their own experiments and interpret data from their investigations on factors that change the rate of hydrogen peroxide decomposition by the enzyme catalase.
Part of the Inquiries in Science™ series.
Materials are sufficient for 30 students working in groups.
