Where do some enzymes work?
Outside of the body.
1 of 15
What are digestive enzymes produced by?
Specialised cells in glands and the lining of the gut. The enzymes pass out of the cells and come in contact with food.
2 of 15
What does digestion involve?
The breakdown of large insoluble molecules into smaller soluble molecules.
3 of 15
What is each reaction controlled by?
A specific enzyme.
4 of 15
What is amylase?
A Carbohydrase.
5 of 15
Where is amylase produced?
Salivary glands, the pancreas and the small intestine.
6 of 15
What does amylase catalyses? Where?
The digestion of starch into sugars in the mouth and small intestine.
7 of 15
Where is protease produced?
By the stomach, pancreas and small intestine.
8 of 15
What does protease catalyses? Where?
The breakdown of proteins into amino acids in the stomach and small intestine.
9 of 15
Where is lipase produced?
Pancreas and small intestine.
10 of 15
What does Lipase catalyses? Where?
The breakdown of lipids to fatty acids and glycerol.
11 of 15
What are lipids?
Fats and oils.
12 of 15
What is fatty acids?
Building blocks to lipids.
13 of 15
What is glycerol?
Building blocks to lipids.
14 of 15
What is a Carbohydrase?
Enzymes which speeds up the breakdown of carbohydrates.
