The percentage amount of `CO_(2)` carried or transported by Hb is

Options

A. 0.1
B. 0.8
C. 0.7
D. 0.23

Answer

To determine the percentage amount of CO₂ carried or transported by hemoglobin (Hb), we can follow these steps:

### Step 1: Understand the forms of CO₂ transport
CO₂ is transported in the blood in three main forms:
1. Dissolved in plasma (about 7-10%)
2. As bicarbonate ions (HCO₃⁻) (about 70%)
3. Bound to hemoglobin as carbaminohemoglobin (about 20-23%)

### Step 2: Focus on the hemoglobin transport
The question specifically asks for the percentage of CO₂ that is transported by hemoglobin. This form of transport is known as carbaminohemoglobin.

### Step 3: Identify the percentage of CO₂ transported by hemoglobin
From the information gathered, we know that approximately 20-23% of CO₂ is transported by hemoglobin as carbaminohemoglobin. However, the question provides options that suggest a different interpretation.

### Step 4: Analyze the options provided
The options given are:
- 0.1
- 0.8
- 0.7
- 0.3

### Step 5: Determine the correct answer
Given the context of the question and the options, the percentage of CO₂ transported by hemoglobin as carbaminohemoglobin is approximately 10%, which can be expressed as 0.1 when converted to a decimal.

### Conclusion
Therefore, the percentage amount of CO₂ carried or transported by hemoglobin is **0.1**.
