Question

Which of the following cell organelles is involved in the formation of primary lysosome?

• A. Ribosome
• B. Microsome
• C. Golgi complex
• D. Centriole

Answer 1

The correct option is C

Golgi complex

The correct option is C.

Explanation of correct option:

1. A subcellular composition, which does one or more specific activities within a cell is known as an organelle.
2. It is a membrane-bound composition found within a cell.
3. Organelles are found in all the eukaryotic cells like plant and animal cells, they are generally absent in prokaryotes, like bacteria.
4. The homogenous, dense, membrane-bound organelles comprising acid hydrolases, and possessing the tendency to dissociate down the polymers of all kinds are known as primary lysosomes.
5. The cell organelles, which take part in the generation of the primary lysosome is the Golgi complex.
6. The enzyme proteins are first developed within the rough endoplasmic reticulum, then these proteins are packaged in a vesicle and transmitted to the Golgi complex.
7. The Golgi complex then eventually develops the digestive enzymes and gives off a small, very specific vesicle, this vesicle is known as a primary lysosome.

Explanation of incorrect options:

Option A:

1. A complex molecule, formed of proteins and ribosomal RNA molecules, which produces a factory for the synthesis of proteins within the cells is a ribosome.
2. Ribosomes play no role in the formation of the primary lysosome.

Option B:

1. The artificial compositions obtained from the fragments of endoplasmic reticulum produced at the time of tissue homogenization are known as microsomes.
2. Microsomes are used to impersonate the work of the endoplasmic reticulum in a test tube and perform the experiments, which need protein synthesis on a membrane.
3. Microsomes have no role in the synthesis of the primary lysosome.

Option D:

1. The paired barrel-shaped organelles situated in the cytoplasm of animals close to the nuclear envelope are centrioles.
2. It performs a function in organizing microtubules, which function as the skeletal system of the cell.
3. It has no role in the synthesis of primary lysosomes.

Final answer: Golgi complex is involved in the formation of the primary lysosome.
