Question 1

Iron is an essential trace element. Its deficiency can lead to anemia. What is the primary biochemical role of iron in the human body that, when impaired, causes the characteristic symptoms of anemia?

Accepted Answer

A. Oxygen transport via hemoglobin — Iron is a critical component of the heme group in hemoglobin, the protein responsible for oxygen transport in red blood cells. In this capacity, iron reversibly binds to oxygen in the lungs and releases it in tissues. A deficiency in iron directly impairs hemoglobin synthesis, leading to reduced oxygen-carrying capacity of the blood, which is the hallmark of anemia.
