AP Biology: Enzyme Review Trivia

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required for a chemical reaction to occur.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts that lower the activation energy of a reaction, thereby increasing the reaction rate.

Front

Define metabolism.

Back

Metabolism is the sum of all chemical reactions that occur within an organism, including catabolic and anabolic pathways.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is an endergonic reaction?

Back

An endergonic reaction is a reaction that requires energy input, resulting in a positive change in free energy (ΔG > 0).

Front

What is an exergonic reaction?

Back

An exergonic reaction is a reaction that releases energy, resulting in a negative change in free energy (ΔG < 0).

Front

What is the difference between catabolic and anabolic pathways?

Back

Catabolic pathways break down molecules to release energy, while anabolic pathways build complex molecules from simpler ones, requiring energy.

Front

What is the significance of the enzyme-substrate complex?

Back

The enzyme-substrate complex is crucial for catalysis, as it stabilizes the transition state and lowers the activation energy.

Front

What happens to enzyme activity at extreme temperatures?

Back

Extreme temperatures can denature enzymes, altering their structure and reducing their activity.

Front

What is feedback inhibition in metabolic pathways?

Back

Feedback inhibition is a regulatory mechanism where the end product of a metabolic pathway inhibits an earlier step, preventing overproduction.
