Albinism is due to hereditary deficiency of enzyme

Options

A. Amylase
B. Carbonic anhydrase
C. Acetyl choline esterase
D. Tyrosinase

Answer

To solve the question regarding the hereditary deficiency of an enzyme that causes albinism, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Albinism**: Albinism is a genetic condition characterized by a deficiency in melanin production, which affects the pigmentation of skin, hair, and eyes.

2. **Identifying the Enzyme Involved**: To determine which enzyme deficiency leads to albinism, we need to look at the options provided:
- **Amylase**: This enzyme is responsible for breaking down starch and glycogen. It is not related to melanin production.
- **Carbonic Anhydrase**: This enzyme helps in the conversion of carbon dioxide to bicarbonate in the blood. It does not play a role in melanin synthesis.
- **Acetylcholine Esterase**: This enzyme breaks down acetylcholine in the nervous system. It is unrelated to pigmentation.
- **Tyrosinase**: This enzyme is crucial for the production of melanin. It catalyzes the conversion of tyrosine to melanin.

3. **Conclusion**: Since albinism is specifically related to a deficiency in melanin production due to a genetic defect, the enzyme that is deficient in individuals with albinism is **tyrosinase**.

4. **Final Answer**: Therefore, the correct answer to the question is **option 3: tyrosinase**.
