Question

The ob mouse becomes obese because it lacks the gene that normally produces?

1) CCK
2) leptin
3) insulin
4) NPY
5) glutamate

Answer 1

Leptin normally regulates appetite by decreasing hunger and giving a feeling of fullness when there is more adipose tissue or fat.

Step-by-step explanation:

In the absence of leptin resistance, leptin normally regulates appetite by decreasing hunger and giving a feeling of fullness when there is more adipose tissue or fat. The secretion of leptin is proportional to the body's fat reserves. When fat reserves are high, more leptin is released, which inhibits appetite and leads to eating less. Conversely, when fat reserves are low, less leptin is released, which increases hunger and leads to eating more.
