What are enzymes made of?
Amino acids
1 of 20
What are enzymes?
A type of biological catalysts. They are also proteins
2 of 20
What do enzymes do?
Help to speed up the breaking down process of food molecules
3 of 20
What does the enzyme Amylase do?
Breaks down startch into sugars
4 of 20
What does the enzyme lipease do?
Breaks down fats into fattacids and glycerol
5 of 20
What does the enzyme protease do?
Breaks down proteins into amino acids
6 of 20
Where is amylase made?
Salivary glands, pancreas and small intestine
7 of 20
Where is lipease made?
Pancreas, small intestine
8 of 20
Where is protease made?
Pancreas, stomach and small intestine
9 of 20
What is the active site?
Where the reaction happens between the substrate and enzyme
10 of 20
What is the substrate-enzyme structure look like?
A lock and key
11 of 20
What happens if the temperature is raised above the optimum temperature or is not close to the optimum pH?
The shape of the active site becomes denatured and the reaction
12 of 20
What reactions are catalysed by enzymes?
Respiration, photosynthesis and digestion
13 of 20
Why does each substrate have a particular enzyme?
Each is enzyme has a specific job, amino acid numbers and orders are a result of this. These cause a different shaped active site
14 of 20
What to happens to enzymes once they have helped one reaction?
They do the process again
15 of 20
What increases the surface area in the small intestine?
The villi
16 of 20
Why does the small intestine need a larger surface area?
So more broken down food molecules can be absorbed
17 of 20
What is used to do mechanical digestion?
Teeth

What is used to do chemical digestion?
Enzymes

What does bile do?
Emulsifiers fat (makes tiny droplets of fat to help digestion
