4. Do the "Bond X" bonds in Figure 4 involve atoms in the amino acid R groups or inthe polypeptide "backbone"/ “main chain" atoms?5. Given Your Answer To "b," are each of the following statements True or False?Be able to explain your reasoning.o Only very specific primary sequences can form a-helices and B-sheets.o Many different primary sequences can form a-helices and B-sheets.Each arrow depicted in Figure 4D represents consecutive amino acids in the primarysequence of the polypeptide, while the different arrows may be formed from aminoacids that are removed from each other in the primary sequence. Each arrow isreferred to as a B-strand, and the structure formed through interaction of the B-strandsis the B-sheet. In a complete protein, other segments of the protein would connect thedifferent B-strands.6. Do the "Bond X" bonds in the B-sheet connect atoms from the same B-strand orneighboring strands? amino acids are joined together bybónds, which are a particularbond.type ofSECONDARY STRUCTUREB sheeta helixamino acidside chainamino acidside chainBond Xhydrogencarbon.oxygennitrogenBond Xcarboncarbon-hydrogenpeptidebond„nitrogen-nitrogenoxygencarbonBFigure 4-10 Essential Cell Biology 3/e (© Garland Science 2010)Figure 4.

The hatched lines connecting atoms in Figure 4 represent the bonds that holdtogether these secondary structures (for example, the bond labeled "Bond X").What types of bonds are these? (If you're having trouble seeing, these bondsare between an oxygen and a hydrogen atom, and a hatched line representsthe same type of bond as the dotted lines you encountered when discussingwater and the macromolecules.)
