Enzymes

Question 1

What are biological catalysts

Answer 1

Enzymes

Question 2

What are the five properties of an enzyme

Answer 2

Enzymes are found and produced in every living cell, enzymes are made of proteine, enzymes speed up chemical reactions, they remain unchanged in chemical reactions and enzymes are specific to their substrate

Question 3

What does it mean when we say that an enzyme is specific

Answer 3

They can only bind to one substance which we call a substrate

Question 4

What is the active site

Answer 4

It is were the substrate and enzyme will bind

Question 5

What are the two types of reactions controlled by enzymes what are they

Answer 5

Degradation (break down) and synthesis (build up)

Question 6

Where are enzymes found

Answer 6

In living cells

Question 7

What is the purpose of an enzyme

Answer 7

To speed up chemical reactions

Question 8

What are two factors that affect ab enzyme

Answer 8

PH and temperature

Question 9

When do enzymes work best

Answer 9

In their optimum conditions

Question 10

What is denaturation

Answer 10

At high temperatures the structure of enzymes are changed and the active site is no longer complimentary to its substrate, this means that the enzyme cannot function. This effect cannot be reversed
