Factors Affecting Enzyme Activity

Question 1

What four factors affect enzyme activity?

Answer 1

1. Protein Structure
2. Substrate Concentration
3. pH
4. Temperature

Question 2

What is denaturation?

Answer 2

Denaturation is the change in shape of an active site due to high temperatures breaking bonds in protein molecules

Question 3

What effect do high temperatures have on enzyme activity?

Answer 3

High temperatures cause a change in the enzymes shape (denaturation), making the enzyme not act properly at too high of a temperature

Question 4

What effect does pH have on enzyme activity?

Answer 4

If an enzyme has a pH level not best suited for it, it’ll have a similar response as it did for temperature

Question 5

What effect does substrate concentration have on enzyme activity?

Answer 5

The enzyme levels and substrate concentration have a positive relationship

Question 6

What is an inhibitor?

Answer 6

An inhibitor is a chemical which interferes with the enzymes functions (some attach to active site)
