Question

what levels of protein structure are represented in this image? select all that apply. tertiary structure quaternary structure primary structure secondary structure

Explanation:

The image shows a protein with alpha - helices and beta - sheets which are characteristic of secondary structure. The overall 3 - D shape of a single polypeptide chain shown also represents tertiary structure. Primary structure is the linear sequence of amino acids which is not shown. Quaternary structure involves multiple polypeptide chains which is not the case here.

Answer:

A. Tertiary structure
D. Secondary structure
