Angiotensinogen is a protein produced by

biology digestion and absorption liver functions of the liver secretory organs

  1. Macula densa cells

  2. Liver cells

  3. Juxtaglomerular cells

  4. Endothelial cells

Show answer
Correct Option: B
Explanation:
Angiotensinogen is a plasma protein produced and secreted by liver cells. It is a sole precursor of all angiotensin peptide. Juxtaglomerular cells secrete renin which acts on angiotensinogen to release angiotensin I and then it is converted to angiotensin II by the action of enzyme angiotensin-converting enzymes.
So, the correct answer is 'Liver cells'.
