What is the difference between rough endplasmic reticulum and smooth endoplasmic reticulum?

Answer 1

Some parts of the ER have ribosomes attached to the cutoplasmic side of the membranes. This is called the RER (Rough Endoplasmic Reticulum). These ribosomes synthesise proteins which are to be secreted from the cell, to form lysosomes or to become part of the cell surface membrane.

Other parts of the ER have no ribosomes attached: SER.

The cisternae (enclosed spaces in the membranes) of SER tend to be more tubular, in contrast to the flattened sacs of RER. SER has many different functions, including the synthesis of cholesterol and of steroid hormones such as testosterone and the breaking down of toxins such as drugs.

Answer 2

Rough ER is so called because it is studded with ribosomes. Rough ER facilitates the manufacture of proteins by the ribosomes that stud it and it also modifies these proteins. Smooth ER is not studded with ribosomes and one of it's main functions is the synthesis of lipids.

Answer 3

ER-moves object in cell to one place to another (not organelles)

Ribosomes- build protein

Answer 4

ribosomes make energy while endoplasmic reticulm are like a highway sustem that transports things and may have little ribosomes attached to them those are called rough endoplasmic reticulm

Answer 5

The Golgi apparatus obtains information from the endoplasmic reticulum to be sent throughout the cell.

Answer 6

They are both used for protein synthesis and are very similar. :)

Answer 7

It's not!!!!! tehee
