All about Smooth Endoplasmic Reticulum

1. Smooth
Endoplasmic Reticulum
Group 4- Eunice Halayahay, Guerica Mariz Peduche
Created by: Roiden Fredrich M. Fernandez IX- Krypton

2. Year Discovered
The endoplasmic reticulum
was discovered in 1945.

3. Who discovered?
Ernest Fullam, Keith Porter, and Albert Claude
discovered Endoplasmic Reticulum.

4. Country
Endoplasmic Reticulum
was discovered in Belgium
at Rockefeller Institute.
Belgium Flag

5. Shape and Size
A tubular network of
cytoplasmic pipelines.
Tubules are about 150
nanometer in diameter.

6. 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.

7. Animal or Plant Cell?
The organelle called
‘endoplasmic reticulum’
occurs in both plants and
animals.

8. 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..

9. 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.

10. Interesting FACT:
Smooth ER is largely associated
with lipid (fat) manufacture,
metabolism, steroid production
and hormone production. It also
has a detoxification function.

11. 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 .
