Alcoholic fermentation uses

Options

A. Ribosomes
B. Golgi bodies
C. Mitochondrial enzymes
D. Cytoplasmic enzymes.

Answer

**Step-by-Step Solution:**

1. **Understanding Alcoholic Fermentation**: Alcoholic fermentation is a biological process that converts sugars into alcohol (ethanol) and carbon dioxide. This process is primarily carried out by yeast and some types of bacteria.

2. **Identifying the Enzyme**: The key enzyme involved in alcoholic fermentation is called pyruvate decarboxylase. This enzyme catalyzes the conversion of pyruvate (derived from glucose) into ethanol and carbon dioxide.

3. **Location of the Enzyme**: Pyruvate decarboxylase operates in the cytoplasm of the cell. This is important because it indicates that the process of alcoholic fermentation occurs in the cytoplasmic environment.

4. **Evaluating the Options**:
- Option A (Ribosome): Ribosomes are involved in protein synthesis, not fermentation.
- Option B (Golgi body): The Golgi apparatus is involved in modifying and packaging proteins, not in fermentation.
- Option C (Mitochondrial enzyme): Mitochondrial enzymes are involved in aerobic respiration, not alcoholic fermentation.
- Option D (Cytoplasmic enzyme): This is the correct option as pyruvate decarboxylase is indeed a cytoplasmic enzyme.

5. **Conclusion**: Based on the information gathered, the correct answer to the question "Alcoholic fermentation uses" is option D, which is a cytoplasmic enzyme.
