11. Use the data below to answer the following question: How much more energy is stored in a gramof fat than in a gram of hydrated glycogen?Fat: 39.1 kJ/gGlycogen: 17.5 kJ/g. In its hydrated form in cells, glycogen binds twice its weight in water.12. Consider a 70-kg man containing 10 kg fat. Given that a gram of fat contains 6.7 times moreenergy than a gram of hydrated glycogen in cells, how much heavier would he have to be to storethe same amount of energy in the form of glycogen?13. Given that glycogen catabolism requires 5.0 kJ/L O2 and protein catabolism requires 4.6 kJ/L O2,what is the maximum percentage error involved in assuming a conversion factor of 4.8 kJ/L O₂ ifrespiration were actually to involve only carbohydrate or only protein?14. If a person's metabolic rate is 8640 kJ/day, what is it in watts? 1 W = 1 J/s.

Which of the following about glycerophospholipids and sphingolipids is incorrect? Select one: A. Both glycerophospholipids and sphingolipids are used as component of cell membrane. OB. Glycerophospholipids have two fatty acids connected to a glycerol backbone with a phosphate polar head group. * C. Both glycerophospholipids and sphingolipids contain at least one fatty acid. D. Sphingolipids have a sphingosine backbone in which a fatty acid can be attached to C1 and a sugar can be attached to C2. E. Ceramides are the precursors of all sphingolipids.
.Would you expect an increase or a decrease of entropy to accompany the hydrolysis of phosphatidylcholine to the constituent parts (glycerol, two fatty acids, phosphoric acid, and choline)? Why?
This experiment separates meat into an acetone-soluble part and an acetone-insoluble part. The calculations are based on the principal components of meat being fat (acetone soluble) and protein (acetone insoluble or fat-free meat in report sheet). More realistically, the principal components of meat are fat, protein, and water. Water is acetone soluble. Based on this information, the calculations correctly calculate what quantity, % fat or % fat-free meat? Is the incorrectly calculated quantity over or under estimated?
10. The first reaction in glycolysis is the phosphorylation of glucose: Pi + Glucose → Glucose-6-phosphate This is a thermodynamically unfavorable process with AGº = +13.8 kJ/mol. In a liver cell at 37 °C the concentration of both phosphate and glucose are normally maintained at about 5 mM each. The equilibrium concentration of glucose-6-phosphate according to the above data is: A. 1.18 x107 B. 8.50 x 104 C. 4.25 x 105 D. 2.21 x 10s E. 1.38 x 108 F. 3.02 X 103 G. 6.75 x 10-6 H. 4.08 x 10 I. 9.15 x106
