- Testosterone, Progesterone, and Cortisol are steroid hormones. They are derived from cholesterol and are lipophilic, allowing them to cross cell membranes easily.
- Glucagon, however, is a peptide hormone, not a steroid hormone. It is synthesized from 102 amino acids and works by binding to receptors on the cell surface.
Thus, the correct answer is (3).
