Enzyme Specificity Quiz

What is the primary role of enzymes in chemical reactions?

• To slow down reactions

• To speed up reactions without being consumed

• To provide energy for reactions

• To change the products of reactions

What is the term used for the specific reactant that an enzyme acts upon?

• Inhibitor

• Substrate

• Product

• Catalyst

What is the active site of an enzyme?

• The part of the enzyme that changes shape

• The part of the enzyme that provides energy

• The part of the enzyme that is consumed in the reaction

• The part of the enzyme that binds to the substrate

How does the sequence of amino acids affect an enzyme?

• It determines the enzyme's color

• It determines the enzyme's shape and function

• It determines the enzyme's temperature

• It determines the enzyme's pH level

What happens to proteins when they denature?

• They lose their shape and function

• They become more stable

• They become more active

• They change color

What type of enzyme breaks down molecules?

• Regulatory enzyme

• Synthesis enzyme

• Catabolic enzyme

• Anabolic enzyme

Which type of enzyme is responsible for building up molecules?

• Catabolic enzyme

• Anabolic enzyme

• Decomposition enzyme

• Hydrolysis enzyme

What is the induced fit model?

• A model where the enzyme and substrate do not interact

• A model where the substrate changes shape to fit the enzyme

• A model where the enzyme changes shape to fit the substrate

• A model where the enzyme is rigid and unchanging

How does the induced fit model differ from the lock and key model?

• The lock and key model suggests flexibility in the enzyme

• The induced fit model suggests a rigid enzyme structure

• The induced fit model suggests flexibility in the enzyme

• The lock and key model suggests the substrate changes shape

Why are enzymes specific to particular substrates?

• Because they can bind to any substrate

• Because they have a specific active site shape

• Because they are consumed in the reaction

• Because they change the substrate's shape
