Amount of `CO_2` transported as bicarbonates, carbamino compounds and dissolved condition respectively is

Options

A. 70%, 23%, 7%
B. 23%, 7%, 70%
C. 70%, 7%, 23%
D. 7%, 23%, 70%

Answer

To solve the question regarding the amount of carbon dioxide (CO₂) transported in different forms, we can break it down into the following steps:

### Step 1: Understand the Forms of CO₂ Transport
Carbon dioxide is transported in the blood in three main forms:
1. **Bicarbonates (HCO₃⁻)**
2. **Carbamino Compounds**
3. **Dissolved CO₂**

### Step 2: Identify the Percentage of CO₂ in Each Form
- **Bicarbonates**: The majority of CO₂ is transported in this form. It accounts for approximately **70%** of the total CO₂ transported in the blood.
- **Carbamino Compounds**: This form includes CO₂ bound to proteins, primarily hemoglobin. It accounts for about **23%** of the total CO₂.
- **Dissolved CO₂**: The least amount of CO₂ is transported in a dissolved state, which is around **7%**.

### Step 3: Summarize the Percentages
Based on the information gathered:
- Bicarbonates: **70%**
- Carbamino Compounds: **23%**
- Dissolved CO₂: **7%**

### Step 4: Choose the Correct Option
From the options provided, the correct representation of the amounts of CO₂ transported in each form is:
- **70% (Bicarbonates), 23% (Carbamino Compounds), 7% (Dissolved CO₂)**

Thus, the answer is the first option: **70%, 23%, and 7%**.
