Enzyme Lesson

Why do enzymes stop working when they denature?

• The disulphide linkages change shape

• The active site changes shape.

• The Van Der Waals forces change shape

• The amino acids change shape

Why does changing the shape of the active site alter the rate of an enzyme reaction?

• The enzyme can no longer form the enzyme-substrate complex.

• The substrate can no longer form the enzyme-substrate complex.

• The enzyme and substrate can no longer form the enzyme-substrate complex.

• It's dead, Jim!

What is the name of the enzyme that breaks down starch?

• Helicase

• Lipase

• Protease

• Amylase

What is meant by "optimal temperature"?

• The temperature where the reaction went slowest.

• The temperature where the reaction stopped

• The temperature where the reaction started.

• The temperature where the reaction went fastest.
