hormones enter target cells and bind to intracellular receptors

STEROID hormones enter target cells and bind to intracellular receptors

Explanation:

Hormones are chemical substances which are secreted mainly by the endocrine gland into the blood and are them distributed by the blood to its target site causing effective changes. There are different classes of hormones and they include:

-eicosanoids.

- steroids.

-amino acid/protein derivatives .

STEROID hormones are any steroid that has the ability to act as a hormone which is mainly a cholesterol derivative. These hormones has the ability to enter its target cells and bind to intracellular receptors. I hope this helps, thanks.
