A cat named Lucullus is so spoiled that he willeat nothing but freshly opened canned tuna. Another cat, Griselda, isgiven only dry cat food by her far less indulgent owner. Canned tunais essentially all protein, whereas dry cat food can be considered 70%carbohydrate and 30% protein. Assuming that these animals haveno other sources of food, what can you say about the differences andsimilarities in their catabolic activities?
Phospholipases show an enhanced activity for a substrateabove the critical micelle concentration. (The critical micelleconcentration, or cmc, is that concentration of a lipid abovewhich micelles begin to form.)a. What type of noncovalent interactions are possiblebetween the lipid and the enzyme at this stage?b. What do these interactions suggest about the structure ofphospholipases?
In healthy adults, the concentration of glucose in blood is approximately80 to 110 milligrams per deciliter (mg/dl). After a carbohydrate-richmeal, however, the concentration may spike to 140 mg/dl. Describe thehormonal action that returns blood glucose to normal.
The absorption of triacylglycerols in the small intestineis an energy-requiring process that involves hydrolyticreactions to yield monoacylglycerol and fatty acids. Aftertheir transport into enterocytes, fatty acids and monoacylglycerol are reconverted into triacylglycerols. Suggest areason why triacylglycerols are not absorbed directlywithout the hydrolytic reactions.

Carbonic anhydrase is strongly inhibited by the drug acetazolamide, which is used as a diuretic (i.e., to increase the production of urine) and to lower excessively high pressure in the eye (due to accumulation of intraocular fluid) in glaucoma. Carbonic anhydrase plays an important role in these and other secretory processes because it participates in regulatingthe pH and bicarbonate content of several body fluids. The experimental curve of initial reaction velocity (as percentage of Vmax ) versus [S] for the carbonic anhydrase reaction is illustrated below (upper curve). When the experiment is repeated in the presence of acetazolamide, the lower curve is obtained. From an inspection of the curves and your knowledge of the kinetic properties of competitive and mixed enzyme inhibitors, determinethe nature of the inhibition by acetazolamide. Explain your reasoning.
