Summary Introduction
Introduction:
The steroid hormones are the biochemical compounds that are formed from cholesterol and are hydrophobic in nature. The steroid hormones are typically the corticoids that include mineralocorticoids, glucocorticoids, and sex corticoids. The examples include testosterone, estrogen, and progesterone.

A patient is prescribed drug for the treatment of his prostate cancer that blocks testosterone from binding to its intracellular receptor. Which of the following drugs has this mechanism of action?
Flutamide
Tamoxifen
Leuprolide
Sunitinib
Place the following steps (showing how a steroid hormone changes the activities of its target cells) in order of what happens first, second, third, fourth, and last. Refer to image.
The hormone-receptor complex enters the nucleus of the cell and binds to the DNA.
The steroid hormone passes through the cell membrane.
The hormone attaches to a receptor in the cytoplasm, forming a hormone-receptor complex.
A gene in the DNA is activated, and transcription and translation take place.
Proteins that alter the cell′s activities, such as enzymes, are made.
2. Place the following steps (showing how a hydrophilic hormone changes the activities of its target cells) in order of what happens first, second, third, and last. Refer to image.
The activity of the target cell is changed by the final enzyme in the cascade.
The second messenger activates or deactivates certain enzymes in a cascade fashion.
A second messenger is activated.
Hormone binds to a receptor protein.
