Microorganisms use hydrogen bonds to attach themselves to the surfaces that they live upon. Many of them lose hold of the surface because of the weak nature of these bonds and end up dying or being washed away. Why don't microbes just use covalent bonds instead? A. Covalent bonds are always permanent bonds; the microbes could never get OFF their surface if they used them. B. Covalent bonds depend on completely giving up or completely accepting an electron to form the bond. This isn't possible for many microbes without dramatically altering their basic molecular composition. C. Covalent bonds typically require enzymes to form/break, whereas hydrogen bonds don't. If covalent bonds were used, it would require much more energy and molecules to be contributed from the cell. Hydrogen bonds don't have these requirements. D. Covalent bonds may have more specific and stringent requirements for what atoms can bond with. This makes for stronger bonds, but also decreases the overall potential for bonds that could readily be created between the microbe and its desired surface. E. C and D Bloom's Level: 5.

A biologist determined the amounts of several amino acids in two separate samples of pure protein. His data stated that Protein A possessed: 7% leucine, 12% alanine, 4% histidine, 2% cysteine, and 5% glycine. Interestingly, Protein B had the same percentages of each of the same amino acids. He concluded, from this data, that Proteins A and B are the same protein. Based on this information and his conclusion, determine which of the following is the correct statement regarding his findings: A. He is correct; they have the same percentages of each amino acid, so they are identical protein molecules. B. He is incorrect; while they may possess the same percentages of each amino acid, his findings say nothing about the order in which the amino acids are put together. The order will dictate the overall structure of the protein, so the two could be very different in shape, even though the amino acid totals are the same. C. He is correct; the order of the amino acids is irrelevant. It's only the total number of each molecule that is important to structure. D. He is incorrect; he hasn't accounted at all for the effects of pH on the composition of the protein and its effects on the individual amino acids. Bloom's Level: 5.
