Explanation / Answer
1. Answer: iron
When a person can not manufacture red blood cells at a proper pace, such that destruction would be managed by production of new blood cells, they are known to be suffering from anemia. There is a fall in the hematocrit value and reduction in the oxygen transport. One of the most common causes of anemia is iron deficiency. This is because of the presence of hemoglobin- which is composed of heme and a globular proteins. Heme contains iron.
