Question

Identify the wrong statements
(A) Erythropoietin is produced by juxtaglomerular cells of the kidney
(B) Leydig cells produce Androgens
(C) Atrial Natriuretic factor, a peptide hormone is secreted by the seminiferous tubules of the testes
(D) Cholecystokinin is produced by gastrointestinal tract
(E) Gastrin acts on intestinal wall and helps in the production of pepsinogen
Choose the most appropriate answer from the options given below :

• (D) and (E) only
• (A) and (B) only
• (C) and (E) only
• (A) and (C) only

Answer 1

The Correct Option is C

The question requires us to identify the incorrect statements among those provided regarding hormone production and secretion. Let's analyze each statement:

1. Statement (A): Erythropoietin is produced by juxtaglomerular cells of the kidney.
   This statement is incorrect. Erythropoietin is actually produced by the interstitial fibroblasts in the kidney, not the juxtaglomerular cells.
2. Statement (B): Leydig cells produce Androgens.
   This statement is correct. Leydig cells, located in the testes, are responsible for the production of androgens, primarily testosterone.
3. Statement (C): Atrial Natriuretic factor, a peptide hormone, is secreted by the seminiferous tubules of the testes.
   This statement is incorrect. Atrial Natriuretic Factor (ANF) is produced by the cardiac atria, not by the seminiferous tubules of the testes.
4. Statement (D): Cholecystokinin is produced by the gastrointestinal tract.
   This statement is correct. Cholecystokinin is a peptide hormone produced by the I-cells in the mucosal lining of the small intestine.
5. Statement (E): Gastrin acts on the intestinal wall and helps in the production of pepsinogen.
   This statement is incorrect. Gastrin acts on the stomach, not the intestinal wall, and stimulates the secretion of gastric acid (HCl) and pepsinogen from the stomach lining.

Based on the above analysis, the incorrect statements are (C) and (E). Thus, the correct choice is:

(C) and (E) only
