What is the job of the liver?
It produces bile which neutralises stomach acid and emulsified fat.
What stores bile before releasing it into the small intestine?
The Gall bladder
What does the pancreas produce and then release into the small intestine?
Protease,amylase and lipase enzymes.
The large intestine is where…
…excess water is absorbed from food.
Name one job that the small intestine does.
Produce protease, amylase and lipase enzymes to complete digestion.

Rectum
Carbohydrases convert carbohydrates into simple sugars. Amylase is an example of a carbohydrase. Name the three places that amylase is made.
In the salivary glands, the pancreas and the small intestine.
Proteases converts proteins into amino acids. Name the three places that proteases are made.

Lipases convert lipids into glycerol and fatty acids. Where are the two places that lipases are made?
