About this printable

This printable guides students through matching organs to the enzymes they produce, completing a table linking food molecules to enzymes and sites of action, interpreting enzyme activity graphs (temperature and pH), and planning a simple investigation (aim, variables, method, safety). It also includes a useful vocabulary panel (enzyme, active site, substrate, product, denaturation) to support scientific language development. Use it to consolidate a lessons on digestion and enzyme action or to prepare students for a practical enzyme experiment.
