Where they differed most
Rewrite for a 12-year-old in under 60 words without making it false: 'Enzymes are biological catalysts that lower the activation energy of reactions by providing an alternative reaction pathway, and are highly specific due to the complementary shape of their active site.'
Enzymes are proteins that speed up chemical reactions in living things. They make reactions easier by offering a path that needs less energy. Each enzyme usually works with specific molecules because its active site has a matching shape.
Enzymes are proteins that help chemical reactions happen faster in living things. They do this by making the reaction easier to start. Each enzyme usually works only with certain substances because its active site has a matching shape.
