ADD BIO: Enzymes and Digestion

HideShow resource information
Where is amylase made?
In the salivary glands, pancreas and small intestine.
1 of 16
Where is protease made?
In the stomach, pancreas and small intestine.
2 of 16
Where is lipase made?
in the pancreas and small intestine.
3 of 16
Where is bile made?
In the liver.
4 of 16
Explain how emulsification helps digestion.
It breaks fat into smaller droplets which gives them a larger surface are for lipase to work on, speeding up digestion.
5 of 16
Specialised cells in the lining of the gut can also produce what?
Digestive enzymes.
6 of 16
What is the salivary gland's role in digestion?
Produces saliva / amylase
7 of 16
What is the pancreas' role in digestion?
Produces enzymes (protease, amylase and lipase) / releases enzymes into the small intestine.
8 of 16
What is the liver's role in digestion?
Produces bile which emulsifies fats and neutralises stomach acids.
9 of 16
Protease breaks down ........... into ...........
Protein, amino acids.
10 of 16
Lipase breaks down ........... into ........... and ...........
fat, glycerol, fatty acids.
11 of 16
Amylase breaks down ........... into ...........
Carbohydrates e.g. starch, sugars.
12 of 16
What is the role of the small intestine?
1) Produces protease, amylase and lipase enzymes to complete digestion. 2) Where digested food is absorbed out of the digestive system into the blood.
13 of 16
What is the role of the gall bladder?
Where bile is stored, before it's released into the small intestine.
14 of 16
What is the role of the large intestine?
Where excess water is absorbed from the food.
15 of 16
What is the role of the stomach?
1) It pummels the food with its muscular walls. 2) It produces protease enzymes, pepsin. 3) Produces hydrochloric acid to kill bacteria and to give the right pH for protease to work (pH 2).
