2.13 pH & Enzyme function

Question 1

What happens to the enzyme when pH is either too high or too low?

Answer 1

Bonds that hold the amino acids will break, leading to the enzyme’s active site changing shape, therefore less reactions

Question 2

What does the pH- Enzyme function graph look like?

Answer 2

• An upside down U starting from 2.5 pH to 13pH
• This is because at too low or too high pH levels, enzymes are fully denatured which means no reactions are happening
