1 Chemical Digestion Ms. Lowrie Biology 11

2 Enzymes  Biological catalysts  Made in ribosomes = proteins  Three types in digestion: Carbohydrase Lipase Protease  Named after organic compound they breakdown

3 Review – Organic Compounds Carbohydrates:  Polysaccharides/starch are composed of … Simple sugars (monosaccharides)  Proteins are composed of … Amino acids  Lipids are composed of … Fatty acids & glycerol

10 Why is bile not included?  Not chemical digestion Chemical bonds aren’t broken  Mechanical digestion Fat is made smaller Broken into smaller fat droplets

11 Review – Starch (Carbs) Starch (polysaccharides) by: salivary amylase Disaccharides by: pancreatic amylase Simple Sugar diffuses into … Capillary

12 Review – Fat Fat by: bile (mechanical) Fat Droplets by: lipase Fatty acids & Glycerol diffuses into … Lacteal

13 Review – Protein Protein (long a.a. chains) by: pepsin Short a.a. chains by: trypsin & erepsin Amino Acids diffuses into … Capillary

14 Lipase Pancreatic amylase Trypsin Erepsin Bile
