Enzymes Quiz

What is the specifically shaped area on an enzyme where substrates can bind?

• Active site

• Inactive site

• Binding site

• Catalytic site

Imagine Nora, Ethan, and Mason are tiny scientists exploring a giant enzyme. What happens when they help a substrate bind to the enzyme?

• They see the substrate being held with strong bonds

• They notice the active site changing its shape

• They observe the substrate being broken down immediately

• They witness the enzyme becoming denatured
