Learning goals
- Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules combine with other elements to form amino acids and other large carbon-based molecules
- Model the conversion of glucose into chemical energy (ATP) through glycolysis, the citric acid cycle, and oxidative phosphorylation
- Explain how the electrochemical proton gradient across the inner mitochondrial membrane drives ATP synthase during chemiosmosis
Before you begin
Identify reactants and products in a simplified chemical process.

Teaching and response guide
- Model the target skill: construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules combine with other elements to form amino acids and other large carbon-based molecules. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Identify reactants and products in a simplified chemical process.
- Discuss an incorrect response using this distinction: Plants also carry out cellular respiration; photosynthesis does not replace it.
Watch for: Plants also carry out cellular respiration; photosynthesis does not replace it.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
