- 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. Explain what is meant by the term, “high energy compound”. Name a thioester molecule that is commonly found in biochemical reactions. Explain why thioesters are “high energy” compounds. Describe the molecular structure of cellulose. How does this structure explain why cellulose forms strong fibers? Explain why digestion of cellulose takes a long time even when catalyzed by an enzyme. The enzyme phosphofructokinase transfers a phosphate from ATP to the hydroxyl group a C1 of fructose. Similar to fructose, water also has a hydroxyl group and the concentration of water is much higher than that of fructose. Explain why the phosphate is transferred to fructose and not to water.Physics written by hand. Determine the solvation shell from alanine. Report this value and discuss it.
