With in the chloroplast enzymes required for protein synthesis are present in

Options

A. Stroma
B. lumen
C. circular DNA
D. granum

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the enzymes required for protein synthesis are located within the chloroplast.

2. **Identifying the Options**: The options provided are:
- Option 1: Stroma
- Option 2: Lumen
- Option 3: Circular DNA
- Option 4: Granum

3. **Analyzing Option 1 (Stroma)**: The stroma is the fluid-filled space surrounding the thylakoids in chloroplasts. It contains enzymes necessary for the synthesis of proteins, as well as other metabolic processes. Therefore, this option is likely correct.

4. **Analyzing Option 2 (Lumen)**: The lumen refers to the space inside the thylakoids. While it is involved in certain processes, it does not contain the enzymes required for protein synthesis. Thus, this option is incorrect.

5. **Analyzing Option 3 (Circular DNA)**: Chloroplasts contain their own circular DNA, which is involved in coding for some proteins. However, the enzymes for protein synthesis are not located in the DNA itself. Therefore, this option is also incorrect.

6. **Analyzing Option 4 (Granum)**: Grana (plural of granum) are stacks of thylakoids where the light-dependent reactions of photosynthesis occur. They do not contain the enzymes for protein synthesis. Hence, this option is incorrect.

7. **Conclusion**: Based on the analysis, the correct answer is Option 1: Stroma, as it is the location within the chloroplast where enzymes necessary for protein synthesis are found.

**Final Answer**: The enzymes required for protein synthesis within the chloroplast are present in the **stroma**.
