GCSE Biology - Digestive Enzymes

⭐️ https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The necessity of breaking down large biological molecules (carbohydrates, proteins, lipids) into smaller, soluble molecules for absorption. 2. The role of enzymes as biological catalysts in speeding up digestion. 3. Carbohydrate Digestion: Breakdown of starch (a polymer of glucose) by amylase into maltose. Breakdown of maltose by maltase into glucose. 4. Protein Digestion: Breakdown of proteins by protease enzymes (like trypsin and pepsin) into amino acids. 5. Lipid Digestion: Breakdown of lipids (fats and oils) by lipase enzymes into glycerol and fatty acids. The role of bile in emulsifying lipids to increase surface area for lipase action (bile is not an enzyme). 6. Locations of Enzyme Production: Amylase: Salivary glands, pancreas, small intestine. Protease: Stomach, pancreas, small intestine. Lipase: Pancreas, small intestine. ** CHAPTERS ** 0:00 Enzymes Involved in Digestion 0:24 Why Digestion is Needed 1:11 Carbohydrate Digestion (Starch) 2:07 Protein Digestion 2:38 Lipid Digestion 2:58 The Role of Bile 3:24 Where Digestive Enzymes are Made ** PLAYLISTS **    • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • Alevel Biology   #GCSE #Biology #study
