Where is bacteria found and where does it live?
Large intestines contain bacteria and they live on the fibre of your diet
What special vitamin does bacteria make?
Vitamin K

Probiotics food like live yogurt
What’s in digestive juice?
Contains enzymes
What are enzymes?
They are special proteins that help break down large molecules of nutrient to smaller molecules
What are enzymes?
They are special proteins that help break down large molecules of nutrient to smaller molecules
Why are enzymes called catalysts?
They speed up the process of digestion without being used up
What are the three main types of enzymes?
Carbohydrase, lipase and protease
What do carbohydrase break down?
They break down carbohydrase into sugar molecules
Where do you find carbohydrase?
In the mouth, stomach and the small intestines
What do protease break down?
The break down proteins into amino acids
Where do you find protease?
Stomach and small intestines
Wht is the whole process of how fat is broken down?
Bile helps lipase so bile breaks down fat into small droplets, lipase digests fat into fatty acids and glycerol
Where do you find lipids?
In the small intestines
What is lipids helped with?
By bile (a substance made from the liver)
