How is the tertiary structure of a protein different from that of a quaternary structure?
A - The tertiary structure contains two beta protein subunits while the quaternary structure consists of two alpha protein subunits.
B - The tertiary structure is a structure of a single protein or a peptide while a quaternary structure has multiple peptide or protein parts.
C - The tertiary structure contains two alpha protein subunits while the quaternary structure consists of two beta protein subunits.
D - The tertiary structure has a 2-D structure while the quaternary structure has a 3-D structure.
Answer: TERTIARY structure is the complete 3-D structure of a protein, or peptide, including all the of its atom arrangements. QUATERNARY structure is the complete 3=D structure of a protein that contains multiple peptides or proteins.
