AI-generated explanation. Check against your textbook.
Explanation: Glucagon is not a steroid hormone; it is a peptide hormone produced by the alpha cells of the pancreas. Steroid hormones (testosterone, cortisol, progesterone) are derived from cholesterol and are lipid-soluble, allowing them to act on intracellular receptors. NCERT classes testosterone and progesterone as male and female sex hormones, and cortisol as a glucocorticoid, all of which are steroids. Glucagon, in contrast, acts through cell surface receptors and influences blood glucose levels by activating signaling pathways. So, among the options, glucagon is the non-steroidal hormone.
🧠 Did You Know? Gluco- has nothing to do with sugar directly; glucagon raises blood sugar by signaling liver cells to release glucose.
💡 NCERT Memory Line: Steroid hormones are cholesterol-derived; peptide hormones like glucagon are not.
