Amount of oxygen present in one gram of haemoglobin is

Options

A. 1.34mL
B. 13.4 mL
C. 134 mL
D. 20 mL

Answer

To determine the amount of oxygen present in one gram of hemoglobin, follow these steps:

1. **Understand the Composition of Hemoglobin**: Hemoglobin is a protein in red blood cells responsible for transporting oxygen. Each gram of hemoglobin has a specific capacity to bind with oxygen.

2. **Identify the Oxygen Binding Capacity**: Research and scientific literature indicate that one gram of hemoglobin can bind with approximately 1.34 milliliters (ml) of oxygen.

3. **Apply the Information**: Since the question specifically asks for the amount of oxygen in one gram of hemoglobin, you can directly state that it is 1.34 ml.

4. **Review the Options**: The options provided are 1.34 ml, 13.4 ml, 134 ml, and 20 ml. Among these, the correct answer, as established, is 1.34 ml.

5. **Conclude the Answer**: Therefore, the amount of oxygen present in one gram of hemoglobin is 1.34 ml.

### Final Answer:
The amount of oxygen present in one gram of hemoglobin is **1.34 ml**.
