Organ System 4 of 35 The different organ system make up... Organisms 5 of 35 Main groups of nutrients Carbohydrates, Proteins, Fats 6 of 35 What is the role of Digestion? To break down food 7 of 35 What is an enzyme? biological catalyst 8 of 35 What is a salivary gland? an enzyme 9 of 35 What else is an Oesophagus called? gullet 10 of 35 The stomach is basically a ... muscular sac 11 of 35 3 important things about the stomach Contracts muscular walls,produces pepsin,produces hydrochloric acid 12 of 35 What happens in the small intestine? Digested food is absorbed into the blood stream. 13 of 35 What else happens in the small intestine? Produces digestive enzymes 14 of 35 Where are most of the digestive enzymes made? Pancrease 15 of 35 Where is Bile made? Liver 16 of 35 Where is Bile stored? Gallblader 17 of 35 Where do you find Villi? Small intestine 18 of 35 What do Villi do? increase the surface area 19 of 35 What does increase in the surface area do? allow more digested food to be absorbed 20 of 35 What organ removes solid waste? Anus 21 of 35 What is the process of removing solid waste called? Defecation 22 of 35 What do Carbohydrates do? provide fuel for respiration 23 of 35 What do proteins do? make cells/tissue structures ans enzymes 24 of 35 What do lipids (fats) do? make hormones and cell membranes 25 of 35 Job of digestive enzymes break down long molecules of food 26 of 35 What are proteins made up of? Amino acids 27 of 35 What do amylase do? help digest food 28 of 35 What are the 2 stages lipids are broken down in? Emulsification, lipase breaks down fat molecules 29 of 35 What is important about an enzyme? Shape 30 of 35 Why is an enzymes shape important? effects how it catalyses a reaction 31 of 35 What effects the rate of a reaction? Temperature,pH,concentration,surface area,pressure 32 of 35 What is it called when an enzyme is in its best temperature and pH? optinum 33 of 35 What does denatured mean? modifying molecular structure of a protein 34 of 35 What happens when something gets denatured? It stops working 35 of 35
