Revision
Revision checklist
Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Biological Molecules: Classify carbohydrates, lipids, proteins and nucleic acids, and test foods for them.
- Protein Structure: Build proteins from amino acids through primary to quaternary structure.
- Enzymes in Depth: Explain specificity, the induced-fit model, and the effects of pH and temperature.
- DNA Structure and Replication: Describe the double helix and the semi-conservative replication mechanism.
- Read each lesson's summary and re-do its practice questions from memory.
