5 Questions
What are some functions of proteins within organisms?
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.
What are proteins composed of?
Proteins are composed of one or more long chains of amino acid residues.
What is a polypeptide?
A linear chain of amino acid residues is called a polypeptide, and a protein contains at least one long polypeptide.
How do proteins differ from one another?
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.
How are the individual amino acid residues in a protein bonded together?
The individual amino acid residues in a protein are bonded together by peptide bonds and adjacent amino acid residues.
