which protein is found in maximum amount ?

Options

A. Catalase
B. Zinc carbonic anhydrase
C. Transferase
D. RUBISCO

Answer

To determine which protein is found in maximum amount, we need to analyze the options given: catalysis, zinc carbonic anhydrase, trascarase, and rubisco.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Catalysis**: This is a general term for the process of accelerating a chemical reaction, not a specific protein.
- **Zinc Carbonic Anhydrase**: This is an enzyme that catalyzes the conversion of carbon dioxide and water to bicarbonate and protons, but it is not the most abundant protein.
- **Trascarase**: This term seems to be a misspelling or misinterpretation; it could refer to a class of enzymes but is not widely recognized.
- **Rubisco**: This stands for ribulose-1,5-bisphosphate carboxylase/oxygenase. It is a crucial enzyme in the Calvin cycle of photosynthesis.

2. **Identifying Rubisco**:
- Rubisco is known to be the most abundant enzyme on Earth. It plays a vital role in the fixation of carbon dioxide during photosynthesis in plants.
- It is responsible for catalyzing the first major step of carbon fixation, which is essential for plant growth and energy production.

3. **Conclusion**:
- Among the options provided, Rubisco is the protein found in the maximum amount globally. It is the primary enzyme involved in the carbon fixation process in plants, making it the most abundant protein.

### Final Answer:
The protein found in maximum amount is **Rubisco**.
