Smooth Endoplasmic ReticulumGroup 4- Eunice Halayahay, Guerica Mariz PeducheCreated by: Roiden Fredrich M. Fernandez IX- Krypton

Year Discovered

The endoplasmic reticulum was discovered in 1945.

Who discovered?

Ernest Fullam, Keith Porter, and Albert Claude

discovered Endoplasmic Reticulum.

Country

Endoplasmic Reticulum was discovered in Belgium

at Rockefeller Institute.

Belgium Flag

Shape and Size

A tubular network of cytoplasmic pipelines.

Tubules are about 150 nanometer in diameter.

Why Smooth ER is smooth?

Because there are no ribosomes on the surface of

this organelle, unlike its couterpart, the rough

endoplasmic reticulum which gets its name from the

presence of the ribosomes.

Animal or Plant Cell?

The organelle called ‘endoplasmic reticulum’ occurs in both plants and

animals.

Role of Smooth ER

Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and

associated products..

Function of Smooth ER

The smooth endoplasmic reticulum has such functions as the

manufacture of steroid hormones in endocrine cells, the

detoxification of organic compounds within liver cells, the release

of glucose in liver cells, and regulating the concentration of

calcium ions within the cisternae space.

Interesting FACT:

Smooth ER is largely associated with lipid (fat) manufacture,

metabolism, steroid production and hormone production. It also

has a detoxification function.

What if the Smooth ER stops working properly?

If the Smooth ER stops working properly then the whole organism

will be affected. When a human consumes alcohol, the Smooth ER

detoxifies the harmful effects of the substance. There would be no

transportation of necessary materials to other organelles.

The cell would stop functioning. The liver would also fail. A cell

needs a Smooth ER and many problems would result without one .
