Gas which is released during catabolic reaction of respiration is_____

Answer

To solve the question "Gas which is released during catabolic reaction of respiration is_____," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- First, we need to differentiate between catabolic and anabolic reactions. Catabolic reactions are those that break down complex substances into simpler ones, releasing energy in the process. Anabolic reactions, on the other hand, build complex substances from simpler ones and consume energy.

2. **Identify the Process of Respiration**:
- Respiration is a catabolic process where glucose and other organic molecules are broken down to release energy. This process occurs in the presence of oxygen (aerobic respiration).

3. **Recognize the Byproducts of Catabolic Reactions**:
- During the catabolic reactions of respiration, glucose is broken down. This breakdown process not only releases energy (in the form of ATP) but also produces byproducts.

4. **Determine the Gas Released**:
- One of the primary byproducts of aerobic respiration is carbon dioxide (CO2). When glucose is metabolized, it reacts with oxygen, and carbon dioxide is released as a waste product.

5. **Conclude the Answer**:
- Therefore, the gas that is released during the catabolic reaction of respiration is carbon dioxide (CO2).

### Final Answer:
The gas which is released during catabolic reaction of respiration is **CO2 (carbon dioxide)**.
