Many enzymes have two essential components, the one protein part called .................... and the other non protein part, which tightly bound to protein part called.............

Explanation

To answer the question regarding the two essential components of many enzymes, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Components of Enzymes**: Enzymes are biological catalysts that facilitate biochemical reactions. They often consist of two main components: a protein part and a non-protein part.

2. **Define the Protein Part**: The protein part of the enzyme is known as the **apoenzyme**. This is the active part of the enzyme that provides the structure necessary for its function.
