4. Why RER membrane is rough in nature?
Answers
Answer:
i guess this is from 9th biology. so here is your answer.
Explanation:
1) The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.
2)Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
3)Membrane biogenesis, the synthesis of specific molecular components and their assembly into cellular membranes, is a critical, major activity in which cells engage throughout their existence.
4)Ribosomes on RER, which give RER its rough appearance.
