Episode notes

Think of your digestive system as a highly efficient chemical factory. You put in a sandwich, and a specialized team of enzymes systematically takes it apart like a lightning-fast pit crew at a Formula 1 race!

In this episode of GCSE Science Unlocked, Lottie and Mr. H tackle Section 4.2.2.1: Digestive Enzymes (Part 2).
