Which of the following ribosomes are engaged in protein synthesis in animal cell:
- Ribosomes which occur on nuclear membrane and E.R.
- Ribosomes of only cytosol
- Ribosomes of only nucleolus and cytosol
- Ribosomes of only mitochondria and cytosol
The Correct Option is A
Solution and Explanation
Ribosomes which occur on nuclear membrane and E.R. are engaged in protein synthesis in animal cells. These ribosomes are associated with the endoplasmic reticulum (ER) and are involved in synthesizing proteins for secretion or membrane insertion.
So, the correct option is (A): Ribosomes which occur on nuclear membrane and E.R.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
