Amino Acids
3 of 25
What can proteins be used for when fats and carohydrates are unavailable
Energy
4 of 25
Are proteins stored in the body?
No
5 of 25
What are proteins that come from animals called?
First Class Proteins
6 of 25
Why are proteins that come from animals important?
They contain all essential amino acids that can't be made by the body.
7 of 25

Enzymes are sometimes referred to as biological catalysts. What is a catalyst?
A catalyst is a substance which increases the speed of a reaction without being changed or used up in the reaction.
9 of 25
What do enzymes have so they can catalyse reactions?
A special shape that fits onto the substance involved in the reaction.
10 of 25
What happens if the substance doesn't match the enzyme shape?
The reaction won't be catalysed.
11 of 25
At what temperature do enzymes in the human body work best?
37oC
12 of 25
What is meant by the optimum Ph of an enzyme?
The optimum Ph is the Ph at which the enzyme works best.
13 of 25
What happens to an enzyme if the temperature is too high or the Ph is too extreme.
The enzyme becomes denatured and the reaction stops.
14 of 25
What is the function of digestive enzymes?
They break down large molecules into smaller molecules.
15 of 25
Which enzyme digests starch?
Amylase.
16 of 25
Which enzyme digests protein?
Protease
17 of 25
Which enzyme digests lipids?

What does bile do?
It neutralises stomach acid and emulsifies fats.
22 of 25
Why are enzymes cheap to use in industry and the home?
They don't need high temperatures to work and can be re-used.
23 of 25
Give and example of a use of enzymes in the home?
