Model Answer
Haemoglobin present in red blood cells carries oxygen to all body cells. Its deficiency would mean:
- Less oxygen is transported to body cells, reducing energy production.
- The person would feel tired and weak.
- Carbon dioxide removal from tissues may also be affected.
- This condition leads to anaemia, causing breathlessness and fatigue.

Explanation
- The key fact is that haemoglobin carries oxygen in red blood cells — state this first.
- Consequences to mention: reduced oxygen supply → less energy → weakness/fatigue → anaemia. Two or three clear consequences are enough for 2 marks.
- Examiners expect the term anaemia to be used.
- Do not write about the heart or blood pressure — stay focused on haemoglobin's role in oxygen transport.
