NEETZoologyChemical Coordination and Integration
Which of the following is an incorrect match regarding the hormone, its chemical nature, and its primary function?
Options
- ASecretin - Steroid - Stimulates secretion of water and bicarbonate ions
- BErythropoietin - Peptide - Stimulates formation of RBCs
- CAtrial natriuretic factor - Peptide - Causes dilation of blood vessels
- DGastrin - Peptide - Stimulates secretion of HCl and pepsinogen
Correct answer
A. Secretin - Steroid - Stimulates secretion of water and bicarbonate ions
Step-by-step solution
Hormones secreted by the gastrointestinal tract, kidney, and heart are peptide, polypeptide, or protein hormones. Secretin is a peptide hormone secreted by the gastrointestinal tract, not a steroid hormone. It acts on the exocrine pancreas and stimulates the secretion of water and bicarbonate ions. Thus, this match is incorrect. Erythropoietin is a peptide hormone from the kidney that stimulates erythropoiesis (formation of RBCs). Atrial natriuretic factor (ANF) is a peptide hormone from the heart that causes dilat
