Question

Which of the following is essential to form haemoglobin in blood?

1. Fats
2. Iron
3. Calcium
4. Protein

Accepted Answer

**Solution:**

1. Haemoglobin is a protein found in red blood cells responsible for carrying oxygen from the lungs to the rest of the body.

2. The key component of haemoglobin is **iron**, which binds oxygen molecules enabling transport.

3. Without adequate iron, the body cannot produce sufficient haemoglobin, leading to iron-deficiency anaemia.

4. Fats, calcium, and protein are important nutrients but are not directly essential for haemoglobin formation.
