The Hierarchy of Protein Structure
A.
Which structure of a protein consists of a linear sequence of amino acids?
- primary
- secondary
- tertiary
- quarternary
B.
Which protein structure gives the protein its actual function?
- primary
- secondary
- tertiary
- quarternary
C.
Which of these describes the quarternary protein structure?
- coiled regions folded into a 3-D shape
- two or more polypeptides bound to each other
- a linear sequence of amino acids
- sequences of amino acids bonded with hydrogen bonds
D.
How does the tertiary structure of a protein differ from the secondary structure?
- The tertiary structure has a 3D shape, while the secondary structure is often folded or pleated.
- The tertiary structure is made of two or more polypeptides, while the secondary structure is made form only one polypeptide.
- The tertiary structure is pleated into an alpha helix, while the secondary structure is completely linear.
- The tertiary structure is a sequence of amino acids, while the secondary structure contains several polypeptides.
