What has a small granular structure that makes protein?
Ribosomes have a small granular structure and are responsible for protein synthesis in cells. They are made of RNA and proteins and can be found in the cytoplasm or attached to the endoplasmic reticulum.
What color is rough and smooth ER?
The rough endoplasmic reticulum appears rough due to the presence of ribosomes on its surface, giving it a granular appearance. The smooth endoplasmic reticulum lacks ribosomes on its surface, giving it a smoother appearance compared to the rough endoplasmic reticulum.
When is agranular attached to granular er?
Agranular ER is attached to granular ER at all times. As granular ER is involved in making membrane and secreting proteins, and agranular ER is involved in making lipids and steroids, the percentage will differ according to the function of the cell.
What are sand paper like dotted with ribosomes concerned with protein synthesis?
Ribosomes are small granular structures found on the endoplasmic reticulum of a cell, resembling sandpaper. They are responsible for protein synthesis, where they read mRNA transcripts to assemble amino acids into proteins according to the genetic code. The ribosomes play a critical role in building proteins that are essential for various cellular functions and processes.
What is agranular ER attached to granular ER?
The agranular ER is involved in making lipids and steroids, the granular is involved in making membranes and secreting proteins as they are extensions of the nuclear membrane. The smooth, agranular, and the rough, granular, are continuations of the Endoplasmic Reticulum.
Why does rough ER look rough under the microscope?
ribosomes attached on the sides of the RER makes it look rough under the microscope .
What organelle is known as the granular appearance?
The organelle known for its granular appearance is the ribosome. Ribosomes are composed of ribosomal RNA and proteins, and they play a crucial role in protein synthesis by translating messenger RNA (mRNA) into polypeptide chains. They can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER, which gives it its characteristic texture.
Is protein synthesis a function of cell membrane?
No, protein synthesis is not a function of the cell membrane. Protein synthesis occurs in the ribosomes of the cell, which are located in the cytoplasm or on the rough endoplasmic reticulum. The cell membrane is mainly involved in regulating the movement of substances in and out of the cell.
What organelle appears as granular material?
Ribosomes .
Is used as a template to make protein?
In the process known as translation proteins are formed in the ribosome when messanger RNA travels through it. This process is predetermined and initiated by a specific sequences of bases. Granular Endoplasmic Reticulum are where these many ribosomes are attactched.
How does smooth ER differ from rough ER?
Rough ER is studded with ribosomes and are involved in modifying proteins. Smooth ER has no ribosomes and is involved with making and modifying fats. Smooth ER lacks the ribosomes that cover the rough ER.
How can you use the word granular in a sentence?
Granular is an adjective to describe something resembling or consisting of small grains or particles. Example sentence:The granular bits of stone dug into my knees when I fell.
