What will happen if smooth endoplasmic reticulum is absent in a cell?

If a cell lacks smooth endoplasmic reticulum, then eventually death can take place as SER are involved in some crucial functions of the body. Explanation: If smooth endoplasmic reticulum is absent in the cells of a person, then there will be abnormality in the production of fats.

Why do we need the smooth endoplasmic reticulum?

The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.

What will happen if ER is removed?

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

What happens if there is no rough ER?

Terms in this set (16) If the ribosomes were not working properly then your cell would not be producing proteins. The substances would not be transported to the Golgi Apparatus, especially proteins. It would not be able to to modify these proteins by adding fats or sugars and folding them.

How does smooth endoplasmic reticulum detoxify?

The detoxification process is performed by the help of the smooth endoplasmic reticulum in liver cells. Liver cells are composed of enzymes that catalyse a number of reactions and can make lipid-soluble drugs and metabolic wastes which are soluble in water, so that these can easily be passed out from the body.

Does the smooth endoplasmic reticulum have ribosomes?

Smooth endoplasmic reticulum, ( SER), has been found involved in steroid synthesis. SER does not have ribosomes on its surface, however, and thus does not participate in the making of proteins.

How does smooth endoplasmic reticulum make lipids?

The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.

What is the significance of presence of SER in liver cells?

The Smooth Endoplasmic Reticulum (SER) of liver cells detoxifies drugs and poisons present in the body. The liver cells detoxify harmful substances by a complex series of chemical reactions. SER releases some enzymes that make the poisons and drugs soluble to the cytosol and are easily excreted out.

Why do liver cells have a lot of smooth ER?

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 endeavour to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.

Does the smooth endoplasmic reticulum transport proteins?

Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes. Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell. …
