Enzymes Review

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

Which suffix is commonly associated with enzymes?

Back

-ase

Front

What is the role of a substrate in enzyme activity?

Back

A substrate is the reactant molecule that an enzyme acts upon to produce a product.

Front

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

Back

The substrate is transformed into a product after the enzyme catalyzes the reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent change itself.

Front

How does pH affect enzyme activity?

Back

Changes in pH can alter the shape of an enzyme's active site, affecting its ability to bind to substrates and catalyze reactions.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction occurs.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times to catalyze the same reaction.

Front

What is the difference between an enzyme and a substrate?

Back

An enzyme is a catalyst that facilitates a reaction, while a substrate is the substance that is transformed during the reaction.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.
