What do you mean by holoenzymes?

Explanation

### Step-by-Step Solution:

1. **Definition of Holoenzyme**: A holoenzyme is a type of conjugated enzyme that is composed of two main components: an apoenzyme and a cofactor (which can be a coenzyme or a prosthetic group).

2. **Understanding Apoenzyme**: The apoenzyme is the protein part of the holoenzyme. It is inactive on its own and requires the presence of a cofactor to become functionally active.

3. **Role of Cofactor**: The cofactor can be a coenzyme (which is a non-protein organic molecule) or a prosthetic group (which is a non-protein molecule that is tightly or covalently bonded to the apoenzyme). The cofactor is essential for the enzyme's activity.
