Question

What is the difference between the smooth endoplasmic reticulum and rough endoplasmic reticulum?

Answer 1

$\huge\red{Answer\: is}$

The main difference between them are

1. For SMOOTH ENDOPLASMIC RETICULUM :-

a.  Ribosomes - Absent

b.  Position - Mainly present near the cell membrane.

c·  Occurrence - Mainly found in lipid forming cells e;g., adipocytes (Fat cells), interstitial cells (of testis), adrenal cortical cells, glycogen storing cells of liver, muscle cells, leucocytes etc.

d·  Origin - Formed from RER by loss of ribosomes.

e·   Component - Mainly formed of tubules.

2. For ROUGH ENDOPLASMIC RETICULUM:-

a. Ribosomes - Present and is also called α-cytomembrane

b.  Position - Mainly present near the nucleus

c.  Occurrence - Mainly found in protein forming cells e;g., pancreatic acinal cells, globlet cells, plasma cells(produce antibodies), Nissl’s granules of nerve cells etc.

d.  Origin - Formed from nuclear membranes.

e.  Component - Mainly formed of cisternae

Rough endoplasmic reticulum (RER):-

1) The endoplasmic reticulum bearing ribosomes on their surface is known as RER.

2) These are actively involved in the protein synthesis.

3) It transports proteins to the different destination like plasma membrane.

Smooth endoplasmic reticulum (SER):-

1) The endoplasmic reticulum that do not bears ribosomes and appear smooth are known as SER.

2) These are major site for the synthesis of lipids.

3) It maintains the calcium ion concentration in the cytosol.
