Topic 1.4.2: Many proteins are enzymes (AQA A-level Biology)

Each of the five lessons included in this lesson bundle are fully-resourced and have been designed to engage and motivate the students whilst covering the following points that are detailed in topic 1.4.2 of the AQA A-level Biology specification:

• Each enzyme lowers 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 concentration, substrate concentration and concentration of competitive and non-competitive inhibitors on the rate of enzyme-controlled reactions

The lessons have been planned to come as a bundle and references are continually made to previous lessons in the topic to support the students in making the important links between structure, properties and actions of these globular proteins.
