B. coenzyme
C. apoenzyme
D. activator

Answer

To answer the question "The inorganic part of an enzyme is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Enzymes**:
- Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are typically proteins that facilitate biochemical reactions.

2. **Components of Enzymes**:
- Enzymes are composed of two main components:
- **Apoenzyme**: This is the protein part of the enzyme that is inactive on its own.
- **Cofactor**: This is a non-protein component that is necessary for the enzyme's activity.

3. **Types of Cofactors**:
- Cofactors can be classified into two categories:
- **Organic Cofactors**: These are called coenzymes (e.g., vitamins) and assist in the enzyme's function.
- **Inorganic Cofactors**: These are minerals or metal ions that also assist in enzyme activity.

4. **Identifying the Inorganic Part**:
- The inorganic part of the enzyme, which is essential for its activity, is referred to as an **activator** or **moiety**.

5. **Final Answer**:
- Therefore, the inorganic part of an enzyme is known as an **activator**.
