Multiple Choice

What is the primary difference between the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER)?

The RER has ribosomes on its surface, while the SER does not.

The RER is found only in animal cells, while the SER is found only in plant cells.

The RER is involved in lipid synthesis, while the SER is involved in protein synthesis.

The RER is responsible for detoxification, while the SER is responsible for calcium storage.

Verified step by step guidance

Understand the structure of the endoplasmic reticulum (ER): The ER is a network of membranes within the cell, divided into two types: rough ER (RER) and smooth ER (SER).

Identify the key structural difference: The rough ER is studded with ribosomes on its cytoplasmic surface, giving it a 'rough' appearance, whereas the smooth ER lacks ribosomes, hence its 'smooth' appearance.

Explore the functions of the rough ER: The presence of ribosomes on the RER is crucial for its role in protein synthesis. Ribosomes are the sites where amino acids are assembled into proteins.

Examine the functions of the smooth ER: The SER is involved in lipid synthesis, metabolism of carbohydrates, detoxification of drugs and poisons, and storage of calcium ions.

Clarify the misconception about cell types: Both RER and SER are found in both plant and animal cells, not restricted to one type of cell.
