Inhibition of photosynthesis due to photorespiration is a type of

Options

A. competitive inhibition
B. non-competitive inhibition
C. uncompetitive inhibition
D. feed back inhibition

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants convert carbon dioxide (CO2) and sunlight into glucose and oxygen (O2). It primarily occurs in the chloroplasts of plant cells.

2. **Understanding Photorespiration**:
- Photorespiration is a process that occurs when the enzyme RuBisCO (Ribulose bisphosphate carboxylase/oxygenase) fixes oxygen instead of carbon dioxide. This leads to the production of CO2 and consumes energy, effectively inhibiting the process of photosynthesis.

3. **Identifying the Type of Inhibition**:
- The inhibition of photosynthesis due to photorespiration is categorized as **competitive inhibition**. In competitive inhibition, an inhibitor (in this case, oxygen) competes with the substrate (carbon dioxide) for the active site of the enzyme (RuBisCO).

4. **Explaining Competitive Inhibition**:
- In competitive inhibition, if the inhibitor binds to the active site of the enzyme, it prevents the substrate from binding. This means that when oxygen occupies the active site, carbon dioxide cannot bind, leading to reduced photosynthesis efficiency.

5. **Conclusion**:
- Therefore, the inhibition of photosynthesis due to photorespiration is a type of **competitive inhibition**.
