AP Bio Insta-Review Topic 3.1*: Enzyme Structure

Front

What are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes speed up chemical reactions by decreasing the activation energy required.

Front

What happens to an enzyme when a substrate binds to it?

Back

The enzyme changes shape, which activates it.

Front

How do enzymes affect the Gibbs free energy (ΔG) of a reaction?

Back

Enzymes have no effect on the change in Gibbs free energy (ΔG) of a reaction.

Front

What is the specific region on an enzyme where the substrate binds?

Back

The substrate binds at the active site of the enzyme.

Front

What is the significance of the active site in enzyme function?

Back

The active site is crucial for the enzyme's ability to bind substrates and catalyze reactions.

Front

What is the term for the model that describes how enzymes and substrates fit together?

Back

The induced fit model describes how enzymes and substrates fit together.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Front

What is a cofactor in relation to enzymes?

Back

A cofactor is a non-protein molecule that assists enzymes in catalyzing reactions.
