Proteins and Their Functions Quiz

Functions of proteins within organisms include catalyzing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another.

Proteins are composed of one or more long chains of amino acid residues.

A linear chain of amino acid residues is called a polypeptide, and a protein contains at least one long polypeptide.

<p>Proteins differ primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and usually results in protein folding into a specific 3D structure that determines its activity.</p> Signup and view all the answers
