The collective shape assumed by all of the chains in a protein containing multiple chains. b. The folding of an individual protein molecule. c. The regular repeated shape of the protein molecules backbone. d. The sequence of amino acids bonded together by peptide bonds.arrow_forwardOnce cooked, egg whites remain in a solid form. However, egg whites that are beaten to form meringue will partially change back to a jellylike form if allowed to stand for a while. Explain these behaviors using the concept of reversible protein denaturation.arrow_forward
