Polarized light passing through a sugar solution is rotated. A polarimeter allows us to measure the size and direction of the rotation. A freshly prepared solution of alpha-D-glucose shows a specific rotation of +112 degrees. Overtime the rotation of the solution decreases and reaches an equilibrium of specific rotation of +52.5 degrees. In contrast, a freshly prepared solution of beta-D-glucose shows a specific rotation of +19 degrees. The rotation of this solution increases overtime to the same value as that...

Q1: What are catabolism and anabolism (4 marks)? Q2: Under aerobic respiration, a molecule glucose is oxidized to generate 36 ATPs in eukaryote cell while 38 ATPs in prokaryote cell. Explain how this difference occurred (6 marks). Q3: Why aerobic respiration could produce more energy (ATP molecules) than anaerobic respiration and fermentation? By using glucose as the substrate, illustrate how ATP molecules are being produced in each case (15 marks). Q4: "Most microbes use carbohydrate (glucose) as the energy sources...

3. Use your textbook to determine the structure of D-Glucose and D-Idose. Are these molecules diastereomers or enatiomers. (Be sure to look up structures in books table of carbohydrates) Explain your choice. 4. Given a molecule of D-glucose and D-Fructose, how many membered ring will each monosaccharide form? Of the members (atoms) how many will be carbon and how many are oxygens for each? Finally, which oxygen is incorporated into the cyclic structure. 5. Show the oxidation (weak oxidizing agent)...

The enzyme xylose isomerase is used industrially for the conversion of the sugar glucose to fructose as depicted by the following reaction scheme and generic rate law: glucose ➞ fructose rate = k [glucose]n For one reaction with a high amount of enzyme present, the concentration of fructose is monitored over the course of a reaction. Time(minutes) [fructose](mol/L) 0.0 0.00 3.9 0.52 7.2 0.95 18.8 2.49 23.5 3.11 What is the order of reaction? A. Zeroth order (n = 0)...

sd s a What is the effect of a United States guota on sugar of Q on the equilibrium in the U.S. sugar market? Hint: The answer depends on whether the quota binds (is low enough to affect the equilibrium) Show how a quota, Q, affects the total supply of sugar in the United States. Determine the American total supply curve with the quota and without the quota. 1.) Use the line drawing tool to draw the American supply curve...
