Secondary revision · Biology Form 3
Chemicals of Life
This topic explores the fundamental chemicals of life: carbohydrates, proteins, lipids, and nucleic acids. Students will identify these molecules, write structural formulas, and learn about hydrolysis and dehydration synthesis. They will prepare reagents like Benedict's solution and perform confirmatory food tests for reducing sugars, proteins, lipids, and starch. This practical knowledge is essential for ECZ exams and builds a strong foundation for understanding biological processes at the molecular level. It aligns with the Zambian CBC's emphasis on hands-on, investigative learning and prepares learners for advanced biology studies.
