The advantages and disadvantages of using enzymes

These revision cards are about the advantages and disadvantages of using enzymes. Each card will cover one advantage or disadvantage of using enzymes. On one side of a card will be an indication of whether the card talks about an advantage or disadvantage (e.g. one card will say on one side: "Advantage 1") - on the other side will be the advantage or disadvantage. 

I would recommend that users of this resource try to learn as many advantages and disadvantages covered in these cards as possible but if users do not think they can do this, I recommend they try to learn 3 advantages and 3 disadvantages. 

To all users using this resource, good luck!

Advantage 1
Enzymes in biological washing powders are very effective at removing stains e.g. blood, grass, gravy
1 of 8
Advantage 2
Biological washing powders can be used at lower temperatures - this saves energy and reduces costs
2 of 8
Advantage 3
Some enzymes are used in medicine to diagnose, control or even cure disease
3 of 8
Advantage 4
In industry, costs of equipment and energy can be reduced
4 of 8
Disadvantage 1
If people misuse washing powders they may have allergic reactions on their skin. The enzymes are enclosed in capsules in the dry powder. Once the powder is dissolved, hands should not be placed in the water
5 of 8
Disadvantage 2
Enzymes may enter waterways via the sewage system
6 of 8
Disadvantage 3
Enzymes denature at the high temperature needed to kill pathogens in the washing
7 of 8
Disadvantage 4
Some fabrics such as wool will be digested by proteases
