Submit Constants 1 Periodic Table You may want to reference (Pages 397- 404) Section 10.3 while completing this problem Part C Determine whether each of the following statements describes the primary, secondary tertiary, or quaternary structure of a protein. Two polypeptide chains are held together by hydrogen bonds Check all that apply. D primary protein structure U secondary protein structure tertiary protein structure D quaternary protein structure Submit Request Answer Part D Hydrogen bonding between amino acids in the same polypeptide gives a col protein Check all that apply. ? primary protein structure secondary protein structure tertiary protein structure quaternary protein structure Submi Provide FeedbackExplanation / Answer
The primary structure is the sequence of the amino acids in the chain and the location of all the disulfide bridges.
Secondary structure is regular conformation assumed by the segment of the protein's backbone when it folds.
The three-dimensional structure of the entire protein.
Two polypeptide chains are held together by hydrogen bonding. These structure are known as quaternary protein structure. Therefore, the correct option is (d) that is quaternary structure.
------------------------------------------------------------------------------------------------------
Generally. less than half of the protein's backbone is arranged in a defined secondary structure as alpha-helix and beta pleated sheet. Most of the rest of the protein though highly ordered, is nonrepetitive. Many of these ordered polypeptide fragments are said to be in coil conformations.
Therefore, the correct option is (b) that is secondary structure.
