What is Prader-Willi syndrome?
a. Altered receptor activity for leptin
b. A genetic disorder resulting in obesity
c. Fat accumulation in the liver of gastric bypass patients
d. A failure to adapt to alternating periods of excess and inadequate energy intake

Question 2
Which of the following is a feature of the lipoprotein lipase enzyme?
a. Its activity decreases after weight loss but then rebounds quickly after resuming normal food intake.
b. Its activity can always increase but cannot decrease and is, in part, controlled by the ratchet effect of metabolism.
c. Its activities in men and women are sex-related and explain the differences in major fat storage regions of the body.
d. Its low activity in obese people explains, in part, the inability to mobilize storage fat for energy when following an energy-restricted diet.
e. The release of upper-body fat that it triggers is more active in women than in men, whereas the release of lower-body fat is similar.
