1. Name and differentiate between two types of Endoplasmic Reticulum.
Answers
Explanation:
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.
The two types of Endoplasmic reticulum are be of two forms- the rough endoplasmic reticulum( RER) and the smooth endoplasmic reticulum( SER).
The differences between RER and SER have been given below:
1. Ribosomes are present on the surface of RER, so it is referred to as 'rough'.
On the other hand, the absence of ribosomes on the surface of SER gives it the term 'smooth'.
2. The RER is mainly composed of tubules and vesicles while the SER has flattened sacs referred to as cisternae.
3. The RER is largely responsible for protein synthesis, folding, modification and its transport.
SER, on the other hand, is involved in the synthesis of fat, glycogen, steroids and also detoxification of chemicals.
