Correct answer and explanation

Correct answer: Iron

Explanation: The metal present in haemoglobin is Iron (Fe). 📚 Other Information: ▪️ Haemoglobin is a protein found in red blood cells (RBCs). ▪️ It helps in the transport of oxygen from lungs to tissues. ▪️ Iron forms a complex with the pigment haem, giving blood its red colour. ▪️ Deficiency of iron leads to anaemia. ▪️ Each haemoglobin molecule can carry four oxygen molecules. ▪️ Iron is obtained from foods like spinach, meat, liver, and lentils. ▪️ The normal haemoglobin range in adults is 13–17 g/dL (men) and 12–15 g/dL (women). ▪️ Vitamin C helps in the absorption of dietary iron.
