What is the function of endoplasmic reticulum Class 9?

What is the function of endoplasmic reticulum Class 9?

Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.

What is the most important function of ER?

The most important function of the endoplasmic reticulum is the process of synthesis of proteins. The proteins are processed by the ribosomes present on the surfaces of the endoplasmic reticulum.

What would happen without the endoplasmic reticulum?

What would happen if there wasn’t an endoplasmic reticulum. As we’ve already covered the ER produces ribosomes,and without these ribosomes the cell would not be able to use synthesis to split and create more cells. It also produces things like steroids and without these the plant cell would die.

Can a cell survive without a er?

Furthermore, in the absence of the RER (Rough Endoplasmic Reticulum), cells cannot synthesize lysosomal enzymes, proteins for extracellular secretion and golgi apparatus as the site of synthesis of these are RER. Consequently, in the absence of all these basic and essential cellular activities, the cells tend to die.

What is the main function of each organelle within the endomembrane system?

The endomembrane system includes the nuclear envelope, lysosomes, vesicles, the ER, and Golgi apparatus, as well as the plasma membrane. These cellular components work together to modify, package, tag, and transport proteins and lipids that form the membranes.

Why is endomembrane system important?

The endomembrane system separates the cell into different compartments, or organelles, such as the nucleus, the endoplasmic reticulum (ER), the Golgi apparatus, and lysosomes (see Table 2.2). The endomembrane system is important for the cell’s compartmental organization to function independently and properly.

What will happen if we remove endoplasmic reticulum?

endoplasmic reticulum serves many functions. thus, without it,all those functions would vanish leaving the cell incapable to manage properly resulting in death.
