Which of These Statements Applies to Leptin

Question

Which of these statements applies to leptin
A)It is absorbed by adipocytes and leads to appetite suppression.
B)It encourages appetite.
C)It targets the thalamus.
D)It is secreted by adipocytes and leads to appetite suppression.

Accepted Answer

Leptin is a hormone that is secreted by adipocytes (fat cells). Its main function is to suppress appetite and promote energy expenditure. Leptin acts on specific receptors in the hypothalamus, which helps to regulate food intake and body weight. Therefore, option D is the correct statement. Options A and B are incorrect, as leptin does not lead to appetite suppression, and it is not an appetite enhancer. Option C is also incorrect, as leptin does not target the thalamus specifically; it acts on receptors in the hypothalamus.
