Question

A series of membrane-enclosed channels studded with ribosomes is called

• A. Lysosomes
• B. Golgi complex
• C. Rough endoplasmic reticulum
• D. Mitochondria

Answer 1

The correct option is C

Rough endoplasmic reticulum

Explanation for correct option:

1. The endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.
2. It is of two types RER and SER. Rough ER (RER) is the endoplasmic reticulum attached to the ribosome and thus involves the formation and transportation of proteins.

Explanation for incorrect options:

1. Lysosomes contain various digestive enzymes.
2. The Golgi complex prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell.
3. Mitochondria is known as the powerhouse of the cell it is present in the cytoplasm.

Conclusion:

A series of membrane-enclosed channels studded with ribosomes is called Rough endoplasmic reticulum.
