Percentage of oxygen supplied by haemoglobin is

Options

A. 0.03
B. 0.7
C. 0.97
D. 1

Answer

To determine the percentage of oxygen supplied by hemoglobin, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Oxygen Transport**: Oxygen is transported in the blood in two primary forms:
- Bound to hemoglobin (in red blood cells)
- Dissolved in plasma (the liquid component of blood)

2. **Percentage of Oxygen Transported by Hemoglobin**:
- The majority of oxygen (approximately 97%) is transported by hemoglobin. This occurs when oxygen binds to hemoglobin to form oxyhemoglobin.
- Only a small percentage (around 3%) of oxygen is transported in a dissolved form in the plasma.

3. **Identifying the Correct Answer**:
- Given the options: 0.03, 0.7, 0.97, and 1, we need to identify which one corresponds to the percentage of oxygen supplied by hemoglobin.
- Since 97% can be expressed as a decimal, it is equivalent to 0.97.

4. **Conclusion**: Therefore, the percentage of oxygen supplied by hemoglobin is **0.97**.

### Final Answer:
The percentage of oxygen supplied by hemoglobin is **0.97**.
