1.7 enzyme action

Question 1

What type of protein is a enzyme

Answer 1

Enzyme is a globular protein

Question 2

What is the function of a catalyst

Answer 2

Alter rate of reaction by making it faster by sometimes a factor of a million

Question 3

How do enzymes help speed up a reaction

Answer 3

They lower the activation energy needed for a reaction to occur meaning less energy is needed for the same reaction and therefore is faster

Question 4

What is the active site of a enzyme

Answer 4

The active site is the specific region of enzyme which is functional and made up of relatively small amino acids. Active site forms a small depression within the much larger enzyme molecule

Question 5

How is the substrate held in place

Answer 5

There are temporary bonds that form between certain amino acids of the active site and groups on the substrate molecule

Question 6

What type of shape does the substrate have

Answer 6

The substrate has a complementary shape to the active site
