AP Biology - Enzymes

Front

What does the highest point in a reaction coordinate diagram represent?

Back

The transition state.

Front

What are organic molecules that temporarily bind to enzymes and enhance an enzyme's ability called?

Back

CoEnzymes.

Front

What does the ability for an enzyme to change its shape upon substrate binding represent?

Back

Induced fit.

Front

What is the area that the substrate fits into on the enzyme called?

Back

Active Site.

Front

What is formed when a substrate and enzyme first interact?

Back

Enzyme-substrate complex.

Front

What is the role of an enzyme in a biochemical reaction?

Back

To lower the activation energy and increase the rate of the reaction.

Front

What is the difference between a cofactor and a coenzyme?

Back

Cofactors are inorganic ions, while coenzymes are organic molecules.

Front

What is an allosteric site?

Back

A site on an enzyme where molecules can bind and affect enzyme activity.

Front

What is the lock and key model of enzyme action?

Back

A model suggesting that the enzyme's active site is exactly complementary to the shape of the substrate.

Front

What is the induced fit model of enzyme action?

Back

A model suggesting that the active site of the enzyme changes shape to fit the substrate.
