Question

Paracrine hormones are eicosanoids that are produced by one group of cells but have their effect by binding to receptors on neighboring cells without circulating through the blood.

A) True
B) False

Answer 1

The correct answer is option A) "True".

Step-by-step explanation:

Paracrine hormones are a type of eicosanoids (signaling molecule), which are characterized for binding and performing its function on nearby cells rather than the cells where they are produced. Two examples of paracrine hormones are estrogens and testosterone. Estrogens are produced by the ovaries, but they perform their function on ovarian follicles. Testosterone is produced by the Leydig cells of the testes, but they perform their function on adjacent seminiferous tubules.
