which of the following statement is incorrect w.r.t. Lysosomes ?

Options

A. Lysosomes are simple tiny spherical sac-like structures
B. They are distributed in the cytoplasm of the cell
C. The enzymes of lysosomes work in basic condition
D. The enzymes of lysosomes are sythesised by RER

Answer

To determine which statement is incorrect with respect to lysosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Lysosomes**:
- Lysosomes are membrane-bound organelles that have a sac-like structure. They are often described as tiny spherical sacs.

2. **Function of Lysosomes**:
- Lysosomes contain hydrolytic enzymes that are crucial for digestion within the cell. These enzymes include lipases (for lipid breakdown), proteases (for protein breakdown), and nucleases (for nucleic acid breakdown).

3. **pH Environment of Lysosomes**:
- Lysosomes operate in an acidic environment, which is essential for the optimal functioning of the hydrolytic enzymes they contain. This is a key point to remember.

4. **Distribution of Lysosomes**:
- Lysosomes are distributed throughout the cytoplasm of the cell, which is a correct statement.

5. **Synthesis of Lysosomal Enzymes**:
- The enzymes found in lysosomes are synthesized by the rough endoplasmic reticulum (RER). This is also a correct statement.

6. **Evaluate the Statements**:
- Now, we need to evaluate the given statements:
- **Statement A**: "Lysosomes are simple tiny spherical sac-like structures." (Correct)
- **Statement B**: "They are distributed in the cytoplasm of the cell." (Correct)
- **Statement C**: "The enzymes of lysosomes work in basic conditions." (Incorrect, as they work in acidic conditions)
- **Statement D**: "The enzymes of lysosomes are synthesized by RER." (Correct)

7. **Identify the Incorrect Statement**:
- The incorrect statement is **Statement C**, which claims that lysosomal enzymes work in basic conditions. In reality, they function optimally in an acidic environment.

### Final Answer:
The incorrect statement with respect to lysosomes is: **"The enzymes of lysosomes work in basic conditions."**
