Front

What do enzymes typically end with?

Back

-ase

Front

What are enzymes primarily made of?

Back

Proteins

Front

In an exergonic reaction, what happens to heat?

Back

Heat is released.

Front

What is the active site of an enzyme?

Back

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

Front

What does an enzyme pathway illustrate?

Back

The series of reactions catalyzed by enzymes in a metabolic pathway.

Front

What is the role of enzymes in metabolic reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.

Front

What is the difference between exergonic and endergonic reactions?

Back

Exergonic reactions release energy, while endergonic reactions require energy input.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

A substance that decreases enzyme activity by binding to the enzyme.

Front

What is the significance of enzyme specificity?

Back

Enzymes are specific to their substrates, ensuring that only certain reactions occur.
