Question

List the steps of steroid hormone action.

Expert Solution

Step 1

Steroids are the main hormones produced from lipids and cholesterol. For example, the reproductive testosterone hormones and the estrogens generated by the gonads (testes and ovaries) are steroid hormones. The steroid hormone aldosterone, engaged in osmoregulation, and cortisol, which plays an important role in metabolism, are formed by the adrenal glands.

Step 2

It involves a six-step process-

Hormone enters inside the cell through diffusion with the plasma membrane.
Inside the cell, a hormone binds with a receptor protein molecule.
The hormone-receptor complex enters inside the nucleus and initiates the process of gene transcription.
Hormone receptor complex binds with chromatin DNA protein complex.
The hormone-receptor complex stimulates mRNA production.
Translated mRNA carries code for a specific protein to be produced.
