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.

Glycogen and fat are two molecules used by human body to store energy. The inside and even outside…

4. Molecules of what substance are given off when glycerol and fatty acids are joined?5. The splitting of a triglyceride (fat) into glycerol and fatty acids involves the addition of the same molecule you removed during dehydration synthesis. This process is called:
Undergoing moderate activity, an average person will generate about 350 kJ of heat per hour. Using the heat of combustion of palmitic acid (AH = -9977.6 kJ/mol) as an approximate value for fatty substances, esti- mate how many grams of fat would be required per day to sustain this level, if all were burned for heat.
