Understanding the Induced Fit Model of Enzyme Action

What is the primary concept behind the induced fit model of enzyme action?

• Enzymes and substrates do not interact.

• Substrates change shape to fit enzymes.

• Enzymes change shape to fit substrates more precisely.

• Enzymes and substrates have identical shapes.

How does the enzyme's shape change affect the reaction it catalyzes?

• It slows down the reaction.

• It prevents the reaction from occurring.

• It speeds up the reaction.

• It has no effect on the reaction.

What happens to the enzyme after the reaction is complete?

• It is used up and cannot be reused.

• It remains unchanged and can catalyze another reaction.

• It becomes inactive.

• It is permanently altered.

What is the purpose of the enzyme changing its shape slightly?

• To destroy the substrate.

• To prevent the substrate from binding.

• To form an even more exact fit with the substrate.

• To form a less exact fit with the substrate.

In the practical demonstration, what role does the hand play?

• The substrate

• The enzyme

• The product

• The active site
