Answer:
-They both are secreted by endocrine glands.
Step-by-step explanation:
Hormones can be defined as signalling molecules, synthesized and secreted by endocrine glands that release their contents directly into blood. One thing is common between steroids and amino acid-based hormones as both amino acid-based hormones and steroid hormones are produced by endocrine glands.
Steroid hormones are lipid-derivatives hormones, such as cortisol, estrogen, and androgen. These hormones can cross the lipid bilayer and receptors for these hormones generally present inside the cells.
Amino acid-based hormones are derived from amino acids, such as thyroid hormone, melatonin, and epinephrine. Receptors for these hormones generally present at cell surface as these hormones cannot cross lipid bilayer.
