What is the job of endoplasmic reticulum?

Answer 1

The endoplasmic reticulum is made of two different types or parts:

Smooth ER - Synthesizes lipids, metabolizes carbohydrates, and detoxifies of drugs and poisons.

Rough ER - ER-bound ribosomes synthesize proteins that are secreted by the cell.

Answer 2

Rough endoplasmic reticulum (RER) is like an assembly line where ribosomes are positioned on to be part of the rapid assembly of proteins.
Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products. Smooth ER is also involved in the production of steroid hormones in the adrenal cortex and endocrine glands.
Smooth ER also plays a large part in detoxifying a number of organic chemicals converting them to safer water-soluble products.
Large amounts of smooth ER are found in liver cells where one of its main functions is to detoxify products of natural metabolism and to endeavor to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
To assist with this, smooth ER can double its surface area within a few days, returning to its normal size when the assault has subsided.
The contraction of muscle cells is triggered by the orderly release of calcium ions. These ions are released from the smooth endoplasmic reticulum.

Answer 3

the job is a transporting system for liquids and nutrients:)

Answer 4

to transport food and proteins around the cell
