Biology Practice Exam Questions And Answers With Verified Solutions If a molecule is produced from atoms that have an electronegativity difference of 0.1, what type of bonds are expected to form? Nonpolar covalent bonds generally form between atoms that have electronegativity differences of less than 0.5. The four major classes of macromolecules Are assembled by the process of condensation Polymers of glucose include: Glycogen, cellulose, and starch, the monomers of which are joined by condensation As a biochemist, you recently discover a new kind of carbohydrate polymer that is resistant to metabolic breakdown. From this information, what function would you expect for this molecule? It would be similar to cellulose and play a role in cell structure. Both cellulose and the new carbohydrate have beta linkages and probably a similar function, which is in cell structure. Examination of a short polypeptide reveals that all of the monomers contain carbon ring or methyl (-CH3) R groups. Therefore, the polypeptide is: Hydrophobic. Amino acid properties can be predicted by their R group and the R groups in these amino acid monomers are all hydrophobic.
