Biochemical Reactions Guided Notes for High School Chemistry
By Hanna K.
A set of guided notes and slides for 9th graders that explicitly teaches how chemical reactions break and form bonds, how energy is absorbed or released, and how catabolic and anabolic pathways differ. Students build vocabulary on activation energy, reactants, products, and enzymes while completing fill-in-the-blank prompts and short explanations.
Customize for your classroom
Teacher Guide & Tips
- Use this as a 45 to 60 minute direct-instruction lesson, pairing the slides with the guided notes so students fill in blanks as you present each section.
- Discussion question: Why does breaking a bond require energy while forming one releases energy, and how does the Law of Conservation of Energy explain where that energy goes?
- Scaffold for struggling readers: Provide the word bank up front and model one example, such as photosynthesis as an endothermic reaction, before students work independently.
- Extension for advanced students: Ask them to predict how a competitive inhibitor would change the rate of an enzyme-catalyzed reaction and to explain the answer using activation energy and active sites.
- Estimated time: Allow about 10 minutes for the energy and bonds section, 15 minutes for pathways and reaction types, and 15 minutes for enzymes and rate factors, plus a short wrap-up.
