Slide 1

Digestive Enzymes

Slide 2

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.

Slide 3

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 )

Slide 4

Enzymes that work on Proteins:

Protease + Proteins Amino Acids

Enzyme (eg. In meat, nuts) (the body can absorb (in stomach) them and use them)

Slide 5

Enzymes that work on Fats

Lipase enzyme + Fats Fatty Acids + Glycerol

(secreted by pancreas) (Butter, Milk) (can be absorbed into body)
