7

What are enzymes used in?

Detergents
Cheese making
Genetic engineering

8

What is meant by the term denatured?

The active site of the enzyme has changed shape and the substrate can no longer fit into it

9

What are enzymes affected by?

Temperature and pH

10

What does optimum mean?

The condition at which something works best

11

What does biological detergent contain?

Enzymes

12

What is an advantage of biological detergent?

Removes stains better
Washes at low temperatures

13

Orange/brown. To blue/black

14

Where is pepsin found in the body?

In the stomach

15

Where are enzymes found?

In the cytoplasm of every living cell

16

What is an enzyme?

It is a biological catalyst that speeds up the rate of reaction without being used up

17

What are enzymes made from?

Protein

18

What is meant by-
Enzymes are specific

They work on only one substrate

19

How are enzymes specific

Because of the shape of their active sites

20

What expression is used to describe the way the substrate fits with the active site?

Like lock and key
