Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

Which suffix is commonly used for enzymes?

Back

-ase

Front

What is the primary function of enzymes in biochemical reactions?

Back

To decrease the activation energy required for the reaction to occur.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy, making it easier for the reaction to occur.

Front

What is the relationship between temperature and enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may decrease due to denaturation.

Front

What happens to enzymes at very high temperatures?

Back

They can become denatured, losing their functional shape and activity.

Front

What is the role of the active site in an enzyme?

Back

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

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times as they are not consumed in the reaction.

Front

What is enzyme specificity?

Back

Enzymes are specific to particular substrates, meaning each enzyme only catalyzes a specific reaction.
