The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds.

WGU C785 Biochemistry Unit Exam Questions Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - answerPrimary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amin...

Epithelial tissue - covers body surfae and lines cavities. Functions primarily as protection, secretion, absorption, excretion, filtration. All cells are exposed to the environment on one side and attached to a basement membrane on other. Proteins - monomeric unit is amino acid (peptide, polypeptide, protein). Functions- enzymes, antibodies, support, keratin, transport molecules, motion, hormones. Peptide bond. metabolism - all the chemical reactions that occur in cell. all biological must ...

"Proton hopping" essentially means that: A) an individual proton "jumps" from one electronegative group to the next. B) a free proton moves from one hydroxyl group of ionized water to the next. C) several protons move between hydrogen bonded water molecules causing the net movement of a photon over a long distance in a short time. D) individual protons are freer to move among and between water molecules in solution. E) hydronium ions are freer to move among and between water molecules ...

Which of the following amino acid would not be commonly found in the middle of a an α-helical domain? - Proline. It is considered a 'helix breaker' and would not be found in an alpha helix; all other residues are nonpolar hydrophobic and could reside in a transmemebrane domain.
