Select the incorrectly matched pair.

Options

A. End products of alcoholic Ethanol fermentation - `+CO_(2)`
B. End products of lactic acid fermentation - Lactic acid `+CO_(2)`
C. Glycolysis -Cytoplasm
D. Key product of glycolysis - Pyruvic acid

Explanation

To solve the question of selecting the incorrectly matched pair regarding fermentation processes, we will analyze the statements provided.

### Step-by-Step Solution:

1. **Identify the Types of Fermentation**:
- There are two main types of fermentation mentioned: alcoholic fermentation and lactic acid fermentation.

2. **Analyze Alcoholic Fermentation**:
- The end products of alcoholic fermentation are ethanol and carbon dioxide. Therefore, if a statement claims that the end product is only carbon dioxide, it is incorrect.

3. **Analyze Lactic Acid Fermentation**:
- The end product of lactic acid fermentation is lactic acid. It does not produce carbon dioxide. The process involves the conversion of pyruvic acid into lactic acid, facilitated by the enzyme lactate dehydrogenase, using NADH as a reducing agent.

4. **Check the Statements**:
- The statement regarding lactic acid fermentation claiming that the end product is "lactic acid plus carbon dioxide" is incorrect. Lactic acid fermentation does not produce carbon dioxide.

5. **Conclusion**:
- The incorrectly matched pair is the one that states the end product of lactic acid fermentation is lactic acid plus carbon dioxide.

### Final Answer:
The incorrectly matched pair is: "The end product of lactic acid fermentation is lactic acid plus carbon dioxide."
