A wasteful, light-induced respiratory process releasing `CO_(2)` is called as

Options

A. Richmond Lang effect
B. Photorespiration
C. PCR
D. Pasteur’s effect

Answer

To solve the question "A wasteful, light-induced respiratory process releasing CO2 is called as," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for a specific term that describes a process which is wasteful, induced by light, and releases carbon dioxide (CO2).

2. **Identify Key Terms**:
- Wasteful process
- Light-induced
- Releases CO2

3. **Consider the Options**:
- A. Richmond-Lange effect
- B. Photorespiration
- C. PCR (Polymerase Chain Reaction)
- D. Pasteur effect

4. **Analyze Each Option**:
- **Richmond-Lange effect**: This is not related to respiration or CO2 release.
- **Photorespiration**: This is a process that occurs in plants where the enzyme Rubisco binds with oxygen instead of carbon dioxide, leading to the release of CO2. It is considered wasteful because it does not produce ATP or sugar efficiently.
- **PCR**: This is a molecular biology technique for amplifying DNA, not related to respiration.
- **Pasteur effect**: This refers to the inhibition of fermentation by oxygen, not specifically a light-induced process.

5. **Select the Correct Answer**: Based on the analysis, the correct answer is **B. Photorespiration**. This process is indeed wasteful, induced by light, and releases CO2.

### Final Answer:
The wasteful, light-induced respiratory process releasing CO2 is called **Photorespiration**.
