Name the type of respiration in which the end products are :
lactic acid

Answer

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the type of respiration that produces lactic acid as an end product.

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

3. **Focus on Anaerobic Respiration**: Since lactic acid is produced when there is a lack of oxygen, we need to focus on anaerobic respiration.

4. **Explain the Process**: In anaerobic respiration, glucose is broken down without oxygen. The process starts with glucose being converted to pyruvate. In the absence of oxygen, pyruvate is then converted into lactic acid, particularly in muscle cells.

5. **Summarize the Findings**: The type of respiration that results in the formation of lactic acid is called anaerobic respiration. This process is commonly observed in muscle cells during intense exercise when oxygen supply is limited.

### Final Answer:
The type of respiration in which the end product is lactic acid is **anaerobic respiration**.
