The suffix-ase to enzyme names was proposed by

Options

A. Duclaux
B. Buchner
C. Northrop
D. Pasteur.

Answer

To answer the question regarding who proposed the suffix "-ase" for enzyme names, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Suffix "-ase":**
The suffix "-ase" is commonly used in biochemistry to denote enzymes. It is added to the name of the substrate that the enzyme acts upon, indicating its function.

2. **Identifying Key Figures:**
The question provides four options: Duclox, Buchner, Nordrop, and Pasteur. We need to evaluate the contributions of each individual to determine who proposed the suffix "-ase".

3. **Evaluating Each Option:**
- **Pasteur:** Known for his work on fermentation and the role of microbes, but not specifically for naming enzymes.
- **Nordrop:** Isolated and crystallized the enzyme pepsin, but did not propose the naming convention.
- **Buchner:** Discovered that fermentation is due to enzymes in yeast, but did not propose the suffix.
- **Duclox:** Proposed the suffix "-ase" in 1898, indicating that it is used to classify enzymes.

4. **Conclusion:**
Based on the evaluation, the correct answer is that the suffix "-ase" was proposed by Duclox.

### Final Answer:
The suffix "-ase" to enzyme names was proposed by Duclox.
