Front

What is the mechanism called when the end product of a metabolic pathway inhibits an earlier step in the pathway?

Back

Feedback inhibition

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 anabolic and catabolic reactions?

Back

Anabolic reactions build larger molecules from smaller ones, while catabolic reactions break down larger molecules into smaller ones.

Front

What is a cofactor?

Back

A non-protein chemical compound that is required for the biological activity of a protein, often an enzyme.

Front

What is a competitive inhibitor?

Back

A substance that competes with the substrate for binding to the active site of an enzyme.

Front

What is allosteric regulation?

Back

A process by which an enzyme's activity is regulated by the binding of an effector molecule at a site other than the active site.
