3 Questions
What is the main function of rough endoplasmic reticulum and how does it achieve this function?
The main function of rough endoplasmic reticulum is protein synthesis. It achieves this function by having ribosomes attached to its surface, which are responsible for synthesizing proteins.
Explain the role of smooth endoplasmic reticulum in the cell and provide an example of its function.
Smooth endoplasmic reticulum plays a crucial role in lipid formation. It forms vesicles for transporting large molecules within the cell. An example of its function is helping in the detoxification of drugs in the liver.
Describe the structural relationship between endoplasmic reticulum, plasma membrane, nuclear membrane, and Golgi apparatus.
The endoplasmic reticulum is continuous with the plasma membrane and nuclear membrane, as well as the Golgi apparatus. This interconnected network allows for the transport of materials and the exchange of substances between these organelles.
Study Notes
Endoplasmic Reticulum (ER)
- ER is a network of interconnected channels.
- ER is continuous with plasma membrane, nuclear membrane, and Golgi apparatus.
- There are two types of ER: Smooth ER and Rough ER.
Smooth Endoplasmic Reticulum (Smooth ER)
- Has no ribosomes attached to it.
- Plays an important role in lipid formation.
- Forms vesicles that transport large molecules to other parts of the cell.
- In liver cells, Smooth ER helps to detoxify drugs.
Rough Endoplasmic Reticulum (Rough ER)
- Has ribosomes attached to it.
- Involved in protein synthesis.
Test your knowledge of the endoplasmic reticulum with this quiz. Explore the structure, functions, and types of ER, including smooth and rough endoplasmic reticulum. Assess your understanding of its role in lipid formation and transporting molecules.
