Smooth Endoplasmic Reticulum

When was it discovered?

1945

Who discovered it?

Keith R. Porter, Albert Claude, Brody Meskers and Ernest F. Fullam

Where is it located?

attached to the rough endoplasmic reticulum near the nucleus and the golgi apparatus

Which cells are they located in?

eukaryotic plant and animal cells

What is the function of the smooth endoplasmic reticulum?

make cellular products like hormones lipids which form all the membranes of organisms

What does the smooth ER metabolize?

natural and ingested toxins

List other functions of the smooth ER

produces glucose transports materials through the inside of the cell

What does it look like?

ribosome-free operating just like a factory

What are the differences between the rough ER and the smooth ER?

rough ER contains ribosomes in it's structure unlike the smooth er while it's function also focuses on the assembly of proteins

Types of reactions that enzymes from the smooth ER catalyze

synthesis of cholesterol, lipids/phospholipids needed by the cell, and steroid hormones

Describe the structure of the SER

system of membranes consisting of cisternae with no ribosomes on its surface
