Which of the following statements is incorrect?a)In ureotelic organism...
Incorrect Statement: In ureotelic organisms, ammonia is not a product of metabolism.
Explanation:
- Ureotelic organisms are those that excrete urea as the primary nitrogenous waste product.
- Ammonia is a highly toxic nitrogenous waste product that is produced during the metabolism of proteins and nucleic acids in cells.
- Ureotelic organisms convert ammonia into less toxic urea, which can be safely excreted.
- Therefore, the statement that ammonia is not a product of metabolism in ureotelic organisms is incorrect.
Other Statements:
- In mammals, some amount of urea may be retained in the kidney matrix to maintain osmolarity: This statement is correct. Urea helps in maintaining the osmotic balance of the blood and tissues.
- In fish, kidneys do not play any significant role in the removal of ammonium ions: This statement is incorrect. Fish excrete ammonia directly through gills as ammonium ions, and the kidneys help in maintaining the electrolyte balance.
- Urea and uric acid are less toxic than ammonia: This statement is correct. Urea and uric acid are less toxic than ammonia and can be safely excreted from the body.
In summary, option A is the incorrect statement as ammonia is a product of metabolism in ureotelic organisms.
