BIOCHEM C785 /BIOCHEM C785 Module 2 Questions And Answers.Primary structure consists of the order of ______ in a protein. These are held together with ______ bonds that are formed by a ______ reaction... . Select one: a. Amino acids, peptide, dehydration b. Nucleotides, peptide, dehydration c. Amino acids, peptide, hydrolysis Incorrect. A part of the response is correct. Amino acids are bonded together to make proteins. The bonds holding these amino acids are referred to as peptide bonds. However, the combination of the two amino acids results in loss of a water molecule referred to as dehydration reaction. Hydrolysis of a peptide bond would result in breaking of the bond rather than building the peptide bond. d. Nucleotides, phosphodiester, dehydration Several types of side chain interactions stabilize the tertiary structure of proteins, including which of the following? Select one: a. Hydrogen bonds, phosphodiester bonds, peptide bonds, covalent bonds b. Ion pairs, peptide bonds, protein bonds, hydrogen bonds. c. Ion pairs, hydrophobic interactions, hydrogen bonds, disulfide bonds Correct! The stability of a tertiary structure of a protein depends on the various interactions and bonds that occur between the side chains of different amino acids. d. Peptide bonds, hydrogen bonds, ester bonds, covalent bonds Which of the following statements is true about the secondary structure of proteins? Select one: a. It includes alpha helices as a common form. b. It includes beta pleated sheets as a common form. c. All of these. d. It involves hydrogen bonding between the backbone atoms. This is partially correct. In order to fulfill their function, proteins must fold in proper, three-dimensional conformations. Which one of the following molecules, available in a cell, is likely to help a protein fold properly? Select one: a. Glycine b. Cysteine c. Chaperone Correct! d. Polymerase Which of the following is true about a misfolded protein? Select one: [Show More]
