Topic 1.4: Proteins (AQA A-level Biology)

All 8 of the lessons that are included in this lesson bundle are highly detailed and will engage and motivate the students whilst covering the content of topic 1.4 of the AQA A-level Biology specification. With proteins playing critical roles in a wide range of living organisms, a clear understanding of the structure and functions of these biological molecules is important for all of the other topics.

The following specification points are covered by the lessons in this bundle:

• The general structure of an amino acid
• A condensation reaction between two amino acids forms a peptide bond
• The formation of dipeptides and polypeptides
• The role of the tertiary structure bonds in the structure of a protein
• The variety of functions of proteins in living organisms
• The relationship between protein structure and function
• The biuret test for proteins
• Enzymes lower the activation energy of the reaction it catalyses
• The induced fit model of enzyme action
• The specificity of enzymes
• The effects of temperature, pH, enzyme and substrate concentration and inhibitors on the rate of enzyme-controlled reactions
