Textbook Question
Chapter 23, Problem 13MC
Hunger, appetite, obesity, and physical activity are interrelated. Thus, (a) hunger sensations arise primarily from the stimulation of receptors in the stomach and intestinal tract in response to the absence of food in these organs; (b) obesity, in most cases, is a result of the abnormally high enzymatic activity of the fat-synthesizing enzymes in adipose tissue; (c) in all cases of obesity, the energy content of the ingested food has exceeded the energy expenditure of the body; (d) in a normal individual, increasing blood glucose concentration increases hunger sensations.

The most common form of malnutrition in children in the world, kwashiorkor, is caused by a diet having ample calories but little protein. The high levels of carbohydrate result in high levels of insulin. What is the effect of high levels of insulin on (a) lipid utilization? (b) protein metabolism? (c) Children suffering from kwashiorkor often have large distended bellies caused by water from the blood leaking into extracellular spaces. Suggest a biochemical basis for this condition.
(a) Choose one water-soluble and one
fat-soluble vitamin. Draw their structures.
Give a reference daily intake for each, in
milligrams or micrograms. Give at least one
metabolic role for each. List the condition
caused by a deficiency of each, or describe
the effects of a deficiency of each. Give a
good dietary source of each. (b) Choose one
