  • Enzyme Blue diagram

    Recognising Enzyme Blue

    Enzyme Blue supports The human digestive system by giving students a diagram they can connect to the specification point being tested.

    What To Explain

    Enzymes have specific active sites and catalyse reactions by helping substrates form products.

    Syllabus Link

    Syllabus link: AQA GCSE Biology 8461, Animal tissues, organs and organ systems.

    Exam Answer Move

    This fits the objective: Explain that digestive enzymes convert large insoluble food molecules into small soluble molecules that can be absorbed into the blood. A creditworthy answer links enzyme structure to substrate specificity and reaction rate.

  • Enzyme Green 3d diagram

    Recognising Enzyme Green 3d
