Find out the correct sentence

Options

A. Enzymes packed in lysosomes are made through RER (Rough Endoplasmic Reticulum)
B. Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectively
C. Endoplasmic reticulum is related with the destruction of plasma membrane
D. Nucleoid is present inside the nucleoplasm of eukaryotic nucleus

Explanation

To determine the correct sentence from the provided options, we will analyze each statement one by one.

### Step 1: Analyze Option A
The first statement claims that the enzymes packed in lysosomes are made through the rough endoplasmic reticulum (RER).

- **Explanation**: Enzymes, particularly digestive enzymes, are indeed synthesized in the RER. The RER is studded with ribosomes, which are responsible for protein synthesis. These proteins are then modified and packaged into vesicles that can become lysosomes.

**Conclusion**: This statement is correct.

### Step 2: Analyze Option B
The second statement suggests that the rough endoplasmic reticulum produces lipids and the smooth endoplasmic reticulum produces proteins.

- **Explanation**: This is incorrect. The rough endoplasmic reticulum is primarily responsible for synthesizing proteins due to the presence of ribosomes, while the smooth endoplasmic reticulum is involved in lipid synthesis.

**Conclusion**: This statement is incorrect.

### Step 3: Analyze Option C
The third statement states that the endoplasmic reticulum is related to the destruction of the plasma membrane.

- **Explanation**: This is also incorrect. The endoplasmic reticulum plays a role in the synthesis of proteins and lipids that are essential for the formation and maintenance of the plasma membrane, rather than its destruction.

**Conclusion**: This statement is incorrect.

### Step 4: Analyze Option D
The fourth statement claims that the nucleoid is present inside the nucleoplasm of a eukaryotic nucleus.

- **Explanation**: This statement is incorrect because the nucleoid is a feature of prokaryotic cells, which lack a defined nucleus. Eukaryotic cells have a true nucleus that is surrounded by a nuclear membrane.

**Conclusion**: This statement is incorrect.

### Final Conclusion
After analyzing all the options, the only correct statement is Option A: "The enzymes that are packed in the lysosomes are made through the rough endoplasmic reticulum."
