Front

The enzyme and substrates have ________ shapes.

Back

complementary shapes

Front

Which color line represents a reaction with an enzyme present?

Back

Blue

Front

Which suffix (word ending) is used in the names of most enzymes?

Back

-ase

Front

What does it mean when an enzyme is denatured?

Back

that the shape is changed of the active site & it no longer works

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up reactions by lowering activation energy.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where substrates bind and reactions occur.

Front

What is a substrate in the context of enzyme activity?

Back

The reactant molecule that an enzyme acts upon.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme is not consumed and can be used again for subsequent reactions.
