Which of the following statements is not correct"

Options

A. Lysosomes have numerous hydrolytic enzymes.
B. The hydrolytie enzymes of lysosomes are active under acidic pH
C. Lysosomes are membrane bound structures
D. Lysosomes are formed by the process of packaging in endoplas1nic reticulum

Answer

To determine which statement about lysosomes is not correct, we can analyze each statement one by one:

1. **Lysosomes have numerous hydrolytic enzymes.**
- **Analysis:** This statement is true. Lysosomes are indeed organelles that contain a variety of hydrolytic enzymes responsible for breaking down different biomolecules.

2. **The hydrolytic enzymes of lysosomes work under acidic pH.**
- **Analysis:** This statement is also true. The enzymes in lysosomes are most active at an acidic pH (around pH 5), which is essential for their function in digestion.

3. **Lysosomes are membrane-bound structures.**
- **Analysis:** This statement is true as well. Lysosomes are indeed membrane-bound organelles, typically consisting of a lipid bilayer that encloses their contents.

4. **Lysosomes are formed by the process of packing in the endoplasmic reticulum.**
- **Analysis:** This statement is incorrect. While lysosomes are membrane-bound structures, they are not formed directly by the endoplasmic reticulum. Instead, they are formed by the Golgi apparatus, which packages the enzymes and materials needed for lysosomal function.

**Conclusion:** The statement that is not correct is: "Lysosomes are formed by the process of packing in the endoplasmic reticulum."
