Question

Common symptoms of iron-deficiency anemia include muscle weakness, shortness of breath, and lightheadedness. Why does iron deficiency cause these symptoms? A. Since iron is required make hemoglobin and myoglobin, iron deficiency decreases the amount of carbon dioxide in the blood and in the muscles. B. Since iron is required for fluid balance, iron deficiency increases the volume of blood that circulates in the body. C. Since iron is required to make hemoglobin and myoglobin, iron deficiency decreases the amount of oxygen in the blood and in the muscles. D. Since iron is required for fluid balance, iron deficiency decreases the volume of blood that circulates in the body.

Answer 1

Answer:

C

Explanation:

Iron is a component of hemoglobin which can transfer Oxygen in our body..if iron is less then it can't take place properly leading to these symptoms..

Answer 2

Iron deficiency cause these symptoms because iron is required to make hemoglobin and myoglobin, iron deficiency decreases the amount of oxygen in the blood and in the muscles.

Explanation:

• Iron-deficiency anemia include muscle weakness, shortness of breath, and lightheadedness.
• In human body, oxygen is transported to organs through haemoglobin present in blood.
• Haemoglobin is a tetrameric protein.
• The main type of haemoglobin in adults is made up of two subunits each of $\alpha$ and $\beta$ polypeptide chains.
• Each polypeptide chain is linked to a heme prosthetic group.
• A heme group is a prosthetic group consisting of a protoporphyrin ring and a central iron (Fe) atom.
• Oxygen binds with haemoglobin and then it is transported.
• Due to Iron deficiency, a deficiency of Oxygen occurs in the body.
• Due to this deficiency of Oxygen, muscle weakness, shortness of breath, and lightheadedness occurs.
