Front

Do enzymes make chemical reactions in living cells take place at lower or higher temperatures?

Back

Enzymes make chemical reactions take place at lower temperatures.

Front

Are enzymes used up in a chemical reaction?

Back

No, enzymes are not used up in a chemical reaction.

Front

What are the reactants of an enzyme-catalyzed reaction called?

Back

The reactants of an enzyme-catalyzed reaction are called substrates.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the molecules upon which enzymes act.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their functional shape.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.
