Enzymes

Front

What is the site called where substrates are brought together in an enzyme-catalyzed reaction?

Back

Active site.

Front

What is the term for a biological catalyst that speeds up chemical reactions?

Back

Enzyme.

Front

What does it mean when we say an enzyme is specific?

Back

Each enzyme only has one substrate that fits its active site.

Front

What is any substance that is acted upon by an enzyme called?

Back

Substrate.

Front

What do we call the substances formed as a result of an enzyme-catalyzed reaction?

Back

Products.

Front

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

Back

Lock and key model.

Front

What happens to the substrate after it binds to the enzyme and the reaction occurs?

Back

It becomes a product.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused.

Front

What is the role of a coenzyme in enzyme activity?

Back

Coenzymes assist enzymes in catalyzing reactions.

Front

What is the effect of temperature on enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low can denature them.
