Question 1

Which of the following disease is caused due to lack of nitrates?&#10;A)Diphtheria&#10;B)Methemoglobinemia&#10;C)Tuberculosis&#10;D)Meningitis

Accepted Answer

Methemoglobinemia can occur due to excessive nitrate intake, which then gets converted to nitrite in the body. Nitrite can oxidize the iron in hemoglobin, forming methemoglobin, which is unable to carry oxygen efficiently. Lack of nitrates is not directly causing diseases; rather, the issue arises from excessive nitrate turning into nitrite. The question might be misleading by suggesting a disease caused by a lack of nitrates, but methemoglobinemia is closely related to nitrate exposure.

Question 2
