steriod hormones - since they are lipophilic and fusses with the membrane to enter teh cell.
The synthesis of steroid hormones primarily takes place in the endoplasmic reticulum and mitochondria of cells. Cholesterol is the precursor molecule for all steroid hormones, which are produced through a series of enzymatic reactions. These hormones play important roles in regulating various physiological processes in the body.
Steroid hormones, such as estrogen and testosterone, are able to enter the target cell and bind to receptors in the nucleus. These hormones are lipid-soluble, allowing them to pass through the cell membrane and directly interact with nuclear receptors to regulate gene transcription.
