Question

Which of the following statements is not correct?

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

Answer 1

The Correct Option is B

To determine which statement about lysosomes is not correct, we need to examine each of the provided statements in detail:

1. Lysosomes have numerous hydrolytic enzymes. This statement is correct. Lysosomes are indeed packed with a variety of hydrolytic enzymes that are crucial for breaking down different types of biological molecules.
2. The hydrolytic enzymes of lysosomes are active under acidic pH. This statement is also correct. These enzymes are optimally active at an acidic pH, which is maintained inside the lysosome.
3. Lysosomes are membrane bound structures. This statement is accurate. Lysosomes are enclosed by a membrane, which segregates their enzymatic contents from the rest of the cell, thereby preventing cellular damage.
4. Lysosomes are formed by the process of packaging in the endoplasmic reticulum. This statement is not correct. Lysosomes are not directly formed by the endoplasmic reticulum. They are generated from the Golgi apparatus where enzymes are processed and packaged into vesicles.

Therefore, the statement "Lysosomes are formed by the process of packaging in the endoplasmic reticulum" is incorrect.

Let's further understand the significance of lysosomes:

• Lysosomes are often termed as the "digestive system" of the cell due to their role in degrading cellular waste materials and cellular components.
• They help in recycling the building blocks of macromolecules and are involved in cellular processes like autophagy.
