This A-Level Biology Proteins Lesson (AQA Specification 3.1.4.1) provides a 1-hour interactive session focused on protein structure and function. Students will explore amino acids as the building blocks of proteins, learning how they form peptide bonds through condensation reactions. The lesson covers the four levels of protein structure (primary, secondary, tertiary, and quaternary) and explains their biological significance, including enzyme function, transport, and structural roles. The session also includes a practical explanation of the Biuret test for proteins, as well as engaging activities and exam-style questions to test knowledge.
Key Highlights:
Detailed PowerPoint presentation
Learning objectives aligned with AQA specification
Knowledge recall and exam-style questions
Visual diagrams and practical examples
Learning objectives:
Explain how amino acids are linked to form polypeptides – the primary structure of proteins.
Explain how polypeptides are arranged to form the secondary structure and then the tertiary structure of a protein.
Explain how the quaternary structure of a protein is formed.
Describe the test for proteins.
