Question

1. Name and differentiate between two types of Endoplasmic Reticulum.


2. Write one function of ribosome.


3. What is membrane biogenesis?

4. Why RER membrane is rough in nature?


plz help me to solve this question​

Answer 1

Answer:

1: Endoplasmic reticulum is a membranous network enclosing a fluid-filled lumen. The two types of endoplamic reticulum are Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum. ... RER has ribosomes attached to its surface. The ribosomes take part in protein synthesis.

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 is the process that involves cell membrane development with the aid of proteins and lipids. The production of these membranes is driven by the endoplasmic reticulum. Membranes synthesized by the membrane biogenesis process help to divide the cell into functional and structural compartments.

4: It possesses rough walls because the ribosomes remain attached to its membranes. On their membranes, rough ER (RER) contains certain ribosome specific, transmembrane glycoproteins, called ribophorins I and II, to which are attached the ribosomes while engaged in polypeptide synthesis.

hope it helps:)

Answer 2

Answer:

question no.1 answer: Endoplasmic reticulum is a membranous network enclosing a fluid-filled lumen. The two types of endoplamic reticulum are Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum. ... SER has ribosomes attached to its surface. The ribosomes take part in protein synthesis.        

question no.2 answer: 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.

question no.3 answer: Membrane biogenesis is the process that involves cell membrane development with the aid of proteins and lipids. The production of these membranes is driven by the endoplasmic reticulum. Membranes synthesized by the membrane biogenesis process help to divide the cell into functional and structural compartments.

question no.4 answer: It possesses rough walls because the ribosomes remain attached to its membranes. On their membranes, rough ER (RER) contains certain ribosome specific, transmembrane glycoproteins, called ribophorins I and II, to which are attached the ribosomes while engaged in polypeptide synthesis.
