Mendel obtained wrinkled seeds in pea due to deposition of sugars instead of starch. It was due to which enzyme :-

Options

A. Amylaae
B. Invertase
C. Diastase
D. Absence of starch branching enzyme

Answer

To solve the question regarding the wrinkled seeds in pea plants and the enzyme responsible for the deposition of sugars instead of starch, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: Mendel's experiments with pea plants revealed that wrinkled seeds are a result of genetic inheritance. The wrinkled phenotype is associated with the storage of sugars rather than starch.

2. **Identify the Enzymes**: The question provides four options for enzymes:
- Amylase
- Invertase
- Diastase
- Absence of starch branching enzyme

3. **Analyze the Role of Each Enzyme**:
- **Amylase**: This enzyme breaks down starch into simpler sugars. It is involved in the breakdown process, not deposition.
- **Invertase**: This enzyme converts sucrose into glucose and fructose. It also does not directly relate to the deposition of sugars in seeds.
- **Diastase**: Similar to amylase, this enzyme breaks down starch into sugars. Again, it is not involved in the deposition process.
- **Absence of Starch Branching Enzyme**: This enzyme is crucial for the synthesis of amylopectin, a component of starch. If this enzyme is absent, starch cannot be properly formed, leading to the accumulation of sugars instead.

4. **Conclude the Correct Answer**: Since the question specifically asks about the deposition of sugars instead of starch, the correct answer is the "absence of starch branching enzyme." This absence leads to the expression of the recessive trait, resulting in wrinkled seeds.

### Final Answer:
The enzyme responsible for the deposition of sugars instead of starch in wrinkled seeds of pea plants is the **absence of starch branching enzyme**.
