Options

D. Conjugation.

Answer

To answer the question regarding the term "ase" added to enzyme names, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Enzyme Naming**: Enzymes are often named based on their substrates (the molecules they act upon) or the reactions they catalyze. For example, the enzyme that breaks down lactose is called lactase.

2. **Identifying the Suffix**: The term "ase" is commonly used as a suffix in the names of enzymes. A suffix is a group of letters added to the end of a word to change its meaning or grammatical function.

3. **Analyzing the Options**:
- **Suffix**: This is a term that is added at the end of a word. Since "ase" is added at the end of enzyme names, this option is plausible.
- **Prefix**: A prefix is added to the beginning of a word. Since "ase" is not at the beginning, this option is incorrect.
- **Interpolation**: This term refers to estimating unknown values based on known values, which is unrelated to enzyme naming.
- **Conjugation**: This term relates to the modification of verbs to express different grammatical categories, which does not apply to enzyme nomenclature.

4. **Conclusion**: Based on the analysis, the correct answer is that "ase" is a suffix.

### Final Answer:
The word "ase" added to enzyme names is a **suffix**.
