Functions of Endoplasmic Reticulum
Answers
Answer:
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
Answer:
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.
there are 2 types of er
1. ser ( smooth)
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
rer ( rough).
The RER is responsible for protein synthesis, modification, packaging, and quality control. We say that the RER makes proteins, but actually most of this is done by the ribosomes attached to its surface. These are called membrane-bound ribosomes.
