Question

Which of the following statements is not correct regarding lysosomes?

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

Answer 1

The correct option is D

Lysosomes are formed by the process of packaging in the endoplasmic reticulum

The correct option is D.

Explanation of the correct option:

1. Proteins, nucleic acids, carbohydrates, and lipids can all be broken down by a variety of enzymes found in lysosomes, which are membrane-enclosed organelles.
2. Repairs to cell membranes, as well as defenses against pathogens, viruses, and other antigens, are the other major functions of the lysosome.
3. The lysosomes undergo autolysis and rupture if the cell is injured.
4. These hydrolytic enzymes are consequently released.
5. Hydrolytic enzymes are housed in membrane-enclosed compartments called lysosomes, which are utilized to safely break down macromolecules inside cells.
6. They comprise roughly 40 different kinds of hydrolytic enzymes, including lipases, phospholipases, glycosidases, phosphatases, sulfatases, proteases, and nucleases.
7. The movement of mTORC1 to the lysosomal surface, where it is activated, is controlled by amino acids.
8. The v-ATPase (vacuolar H+-ATPase)-Ragulator (LAMTOR1-3)-Rag GTPase complex is in the inactive conformation under low amino acids (left) and is unable to connect to mTORC1, resulting in its distribution in the cytoplasm.
9. Once their own cell has been digested by the secreted enzymes, the cell eventually dies.
10. They are therefore known as the cell's suicide sacks.

Final answer: Lysosomes are formed by the process of packaging in the endoplasmic reticulum statement is not correct regarding lysosomes.
