What cellular structures make the outer surface of the rough endoplasmic reticulum appear rough
Ribosomes give the outer surface of the rough endoplasmic reticulum a rough appearance.
are what make rough endoplasmic reticulum look “rough” under a microscopic lens.
b Description: ribosomes.
The correct answer is D. Description: Rough endoplasmic reticulum appears “rough” (see 1st photo) under the electron microscope objective compared to smooth endoplasmic reticulum (see 2nd photo). The small grey/black dots are the ribosomes connected to the ER, helping in the translation of RNA into protein.
Due to the existence of ribosomes on the surface of the endoplasmic reticulum.
Ribosomes are connected to the surface of endoplasmic reticulum (ER) due to which their surface looks rough and hence these ER are called rough endoplasmic reticulum. Whereas in case of smooth endoplasmic reticulum, the surface is devoid of the ribosomes which are protein making particles. Under the microscope lens, ribosomes can be quickly recognized and hence, rough endoplasmic reticulum (RER) can be identified with smooth endoplasmic reticulum (SER).
alternative B Rough endoplasmic reticulum → Golgi apparatus → plasma membrane Description: The pathway used to produce and export proteins from the cell is the rough endoplasmic reticulum which has ribosomes. After that, it is moved to the Golgi apparatus. The Golgi apparatus processes it and forms a bubble. These bubbles are then transported to the plasma membrane.
The rough endoplasmic reticulum looks “rough” under a microscopic lens due to the fact that it actually has ribosomes attached to its surface. Description: The rough endoplasmic reticulum (RER) is a membrane organelle discovered in the cytoplasm of eukaryotic cells, which actually has ribosomes attached to its outer surface. The name, rough endoplasmic reticulum. It has a crucial role in protein synthesis. In ribosomes, proteins are made. The smooth endoplasmic reticulum (SER) is not made up of ribosomes. It has an important role in the synthesis and storage of lipids. Proteins made on the ribosomes are packaged into ampoules and transported to the Golgi apparatus via the rough endoplasmic reticulum. The Golgi apparatus, located next to the RER, personalizes, transports and packages proteins to ship them to specific locations.
The rough ER actually has ribosomes attached to it.
