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

Analysis of each statement:
A. Erythropoietin production: The kidneys, specifically interstitial fibroblasts in the renal cortex adjacent to the proximal convoluted tubule, are the primary producers of Erythropoietin (EPO).
B. Leydig cell function: Leydig cells within the testes synthesize androgens, including testosterone. This statement is accurate.
C. Atrial Natriuretic factor secretion: Atrial Natriuretic Peptide (ANP) is released by the heart's atria, not the seminiferous tubules of the testes (which are involved in sperm production). This statement is inaccurate.
D. Cholecystokinin production: Cholecystokinin (CCK) is a hormone generated by duodenal cells, located in the gastrointestinal tract. This statement is accurate.
E. Gastrin function: Gastrin, a hormone produced by the stomach lining, stimulates gastric acid and pepsinogen secretion. Its action is directed at the stomach's parietal cells, not the intestinal wall, to promote pepsinogen secretion. This statement is inaccurate.
Therefore, the correct statements are B, and D.
