P1: Which letter represents the enzyme? (click on letter)

P1: Which number represents the active site of an enzyme?

P1: Select the molecule that represents the products that result after an enzymatic reaction.

P1: Enzymes are reusable - meaning they will continue to react with any substrate present.

• true

• false

P2: Why are enzymes said to work like a lock and key?

• Enzymes can bind to any substrate regardless of shape.
• Enzymes change shape to fit any substrate like a flexible mold.
• Enzymes work by breaking down all types of molecules without specificity.
• Enzymes specific shapes allow them to bind only to specific substrates.
