Where does anaerobic respiration occur in animals ?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Anaerobic Respiration**: Anaerobic respiration is a metabolic process that occurs in the absence of oxygen. It allows organisms to convert glucose into energy (ATP) without using oxygen.

2. **Energy Yield**: This process produces less energy compared to aerobic respiration. In anaerobic respiration, the end products are typically ethanol (in yeast) or lactic acid (in animals).

3. **Location in Animals**: In animals, anaerobic respiration primarily occurs in muscle cells.
