Question

glut1 is a membrane transport protein that is used by cells to move glucose along its concentration gradient, and across the membrane. it is made of a single polypeptide chain, that is embedded in the cell membrane. based on this information, i would expect to find the following levels of protein folding in glut1 (choose all that apply):

Explanation:

GLUT1 is a single - polypeptide chain protein. All proteins have a primary structure which is the linear sequence of amino acids. It also has a secondary structure formed by local folding into alpha - helices or beta - sheets. The overall 3 - D folding gives it a tertiary structure. Since it is a single polypeptide chain, it does not have a quaternary structure (which requires multiple polypeptide subunits).

Answer:

Primary, Secondary, Tertiary
