Name the chemical energy released during respiration .

Explanation

**Step-by-Step Solution:**

1. **Understanding Respiration**: Respiration is a biological process that involves the breakdown of glucose (or other substrates) to release energy. It is primarily a catabolic process, meaning it breaks down larger molecules into smaller ones.

2. **Identifying the Substrate**: The primary substrate for respiration is glucose, which is a simple sugar and a carbohydrate. It serves as the main fuel for cellular respiration.

3. **Types of Respiration**: There are two main types of respiration: aerobic and anaerobic. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration occurs in the absence of oxygen.
