A protein's alpha helices and beta sheets fold together to create an overall shape at the level of protein structure. A protein's alpha helices and beta sheets fold together to create an overall shape at the level of protein structure. A. first B.second C. third D. fourth

C. third

Explanation:

A protein has four levels of structure:

First: conformed by the linear sequence of amino acids linked by peptide bonds. Secondary:  is the folding of the polypeptide chain and it cam have two shapes: α-helix and the β-pleated sheet.Third: is the spatial arrangement of amino acids after they form the α-helix and the β-pleated sheet.Fourth: when a protein is formed by different polypeptide chains
