O inhibits the transpeptidation reaction in peptidoglycan biosynthesis. O blocks the addition of the pentapeptide chain during peptidoglycan biosynthesis. O inhibits the transglycosylase reaction in peptidoglycan biosynthesis. QUESTION 98 Ergot and aflatoxin are toxins sometimes found in grains contaminated with fungi. O True O FalseWhat role do glycocalyces play in the ability of bacteria to survive and cause disease? ( this answer should have at least 6 functions of a glycocalyx. Each function should describe the mechanism that allows the glycocalyx to help the bacteria survive and/or cause disease.)PART II: Short Answer 21. Explain what it means for an active site to have electronic and shape complementary. Give hypothetical examples of each. A researcher is studying three different synthetic collagens. Collagen A is made of (Pro-Gly- Hyp)10, Collagen B is made of (Pro-Gly-Flp)10, and Collagen C is made of (Pro-Gly-Thr)io. Based on the collagen studies we did in class, which one (A, B, or C) B a) b) ( is the most like normal collagen - would be the most stable and why - because it contain fluorine which is very electronegative would be the least stable and why- c is the least stable

- In the 1860s, Louis Pasteur noticed that when headded O2 to a culture of yeast growing anaerobically onglucose, the rate of glucose consumption declined dra-matically. Explain the basis for this result, which is knownas the Pasteur effect.The following four chemicals commonly found in defined growth media contain all of the necessary atomic macronutrients, namely C, O, N, H, S and P, which microbes require: glucose (C6H12O6), K2HPO4, MgSO4.7H2O, and (NH4)HPO4. Part a. Create a simple diagram to map which growth media chemical contributes atoms to which of the four biological macromolecules (amino acids, polysaccharides, lipids, and ribonucleic acids). Part b. Consider a cell culture broth that originally (before inoculation with cells) contains 5.0 gr/L glucose (C6H12O6), 1.2 gr/L K2HPO4, 0.3 gr/L MgSO4∙7H2O, and 1.0 gr/L (NH4)HPO4. Create a table showing how much of each of the different atoms (C, H, O, K, P, Mg, S, N) are available for incorporation into cell macromolecules (assume 50% of the glucose is catabolized, while the remainder goes for energy (respiration). Express your answers with units of grams of atomic species / liter of culture broth.5- 14. Why 15. When bacteria growing at 20°C are warmed to 30°C, are they more likely to synthesize membrane lipids with (a) saturated or unsaturated fatty acids, and (b) short-chain or long-chain fatty acids?
