Give appropriate biological / technical terms for the following:
A common phase in both aerobic and anaerobic respiration.

Explanation

### Step-by-Step Solution:

1. **Understanding Respiration**: Respiration is a biochemical process where glucose is broken down to release energy. This process can occur in two main ways: in the presence of oxygen (aerobic respiration) and in the absence of oxygen (anaerobic respiration).

2. **Identifying the Common Phase**: Both aerobic and anaerobic respiration begin with the breakdown of glucose. This initial breakdown is crucial for both types of respiration.

3. **Glycolysis**: The common phase in both aerobic and anaerobic respiration is known as glycolysis. During glycolysis, glucose is converted into two molecules of pyruvate, along with the release of energy.
