Expert Answer

Step 1

Estrogen, testosterone, and cortisol are examples of steroid hormones. It is fat-soluble molecules derived from cholesterol. It acts on cells by passing through the cell membrane and enter the nucleus to bind DNA for initiating gene transcription.

Step 2

Steroid hormones cause changes within a cell by passing through the cell membrane of the target cell. Steroid hormones can do this because they are fat-soluble but non-steroid are not fat-soluble so they can’t.

The cell membrane is composed of a phospholipid bilayer which prevents fat insoluble molecules to diffuse into the cell. When steroid molecules enter into the cell it binds with a specific receptor. The receptor bounds to steroid hormone it travels into the nucleus and binds to another specific receptor on the chromatin. When it'...
