How much amount of oxygen can bind to one gram of haemoglobin?

Options

A. 20 ml
B. 1.34 ml
C. 40 ml
D. 13.4 ml

Answer

To determine how much oxygen can bind to one gram of hemoglobin, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. The amount of oxygen that hemoglobin can carry is crucial for understanding respiratory physiology.

2. **Know the Average Hemoglobin Content**: In a normal and healthy person, the average hemoglobin concentration in blood is approximately 15 grams per 100 ml of blood.

3. **Determine the Oxygen Binding Capacity**: It is known that one gram of hemoglobin can bind to approximately 1.34 ml of oxygen (O2).

4. **Calculate the Oxygen Binding for One Gram**: Since we are interested in how much oxygen binds to one gram of hemoglobin, we can directly use the known value:
- **Oxygen binding capacity of 1 gram of hemoglobin = 1.34 ml of O2**.

5. **Identify the Correct Option**: Based on the options provided:
- Option A: 20 ml
- Option B: 1.34 ml
- Option C: 40 ml
- Option D: 13.4 ml
- The correct answer is **Option B: 1.34 ml**.

### Final Answer:
The amount of oxygen that can bind to one gram of hemoglobin is **1.34 ml**.
