Dr. Sanders was excited to observe the effects of leptin on her obese laboratory mice and began to explore ways that leptin could be used to help people lose weight. It is likely that Dr. Sanders will
A) be equally successful with humans as with mice, once the side effects of leptin are controlled.
B) not be successful with humans, because humans do not make leptin.
C) not be successful with humans, because obese humans are already producing high amounts of leptin and adding more would not help them lose weight.
D) not be successful with humans, because obese humans do not have receptors for leptin.

Question

Quizplus · Accepted Answer

While leptin has been shown to be effective in reducing weight in mice, many obese humans are already producing high levels of leptin, and adding more would not necessarily result in weight loss. Additionally, some obese humans have developed a resistance to leptin, making it less effective even if administered in high doses. Therefore, it is unlikely that leptin would be as effective in humans as it is in mice.
