Lyases/Ligases perform breakdown reacting

Explanation

### Step-by-Step Solution:

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They can be classified into different categories based on their functions.

2. **Defining Lyases**: Lyases are a specific class of enzymes that catalyze the removal of groups from substrates without the use of water (i.e., not through hydrolysis). This process often results in the formation of double bonds in the substrate.

3. **Defining Ligases**: Ligases, on the other hand, are enzymes that catalyze the joining of two molecules or substrates. They typically facilitate the formation of bonds such as C-O, C-S, or C-N, effectively linking two compounds together.
