Digestive Enzymes

Our food is made up of: Carbohydrates: Bread, Pasta, Potato Protein: Meat, Nuts, Lentils Fats: Butter, Milk Our body needs to digest them – turn them into a form that can be absorbed into the blood and used by cells. Enzymes make this possible.

Look closely at the 3 digestion equations: Enzymes that work on carbohydrates: Amylase + Starch Maltose Enzyme (in pasta, bread (a form of sugar that can be (in saliva)carbohydrate) absorbed by the body )

Enzymes that work on Proteins: Protease + Proteins Amino Acids Enzyme (eg. In meat, nuts) (the body can absorb (in stomach)them and use them)

Enzymes that work on Fats: Lipase enzyme + Fats Fatty Acids + Glycerol (secreted by pancreas) (Butter, Milk) (can be absorbed into body) Enzyme action animation
