8I: Enzyme Activity and Factors Quiz

Which of the following factors can affect the activity of an enzyme?

• Temperature

• pH

• Concentration of enzymes

• nothing, they function in any conditions

What happens to an enzyme when it is denatured?

• It becomes more active

• It loses its shape and function

• It becomes a substrate

• It doubles its activity

Explain why extreme pH levels can denature an enzyme.

• They provide more substrates

• They alter the enzyme's active site

• They increase enzyme concentration

• They stabilize the enzyme structure

What is the term used to describe the specific region of an enzyme where a substrate binds?

• Active site

• Inhibitor site

• Reaction site

• Binding site

How does a non-competitive inhibitor affect enzyme activity?

• It binds to the active site

• It changes the shape of the enzyme

• It increases substrate concentration

• It enhances enzyme activity
