Asteroid hormone reaches its target cell. which event happens next?
a. it binds itself to the receptors on the surface of the cell membrane, which activates enzymes inside the cell.
b. it passes through the cell membrane and attaches itself to a receptor protein inside the cell.
c. it passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.

The correct answer is option B.

Explanation:

Steroid hormones are cholesterol driven fat soluble molecule, produced by endocrine glands and organs and secreted into the blood to reach target cells.

Steroid hormones can pass through the cell membranes because steroid hormones are hydrophobic or fat soluble. Cell membranes are made up of a phospholipid bilayer that allows fat-soluble molecules to pass through it.

Steroid hormones enter through the cell membrane of the cell and bind with a specific receptor present in the cytoplasm.  This receptor bound hormone later travels in the nucleus.

Thus, the correct answer is option B.
