mitochondrial proteins
coz it is formed in the mitochondria
Rough ER does not synthesis proteins.Proteins are synthesized in ribosomes.
Proteins are mainly synthesized in the Rough Endoplasmic Reticulum, or Rough ER
no
The liver synthesizes several kinds of protein compounds.The rest are synthesized at the Ribosomes of the Rough Endoplasmic Reticulum.The Rough ER synthesizes proteins.
Several types of molecules are produced. Important product is proteins produced by ribosomes on it
It will be on the cytoplasmic side of the ER
Yes, where? The first R in 'RER' stands for rough as in 'rough endoplasmic reticulum'. Compare this to 'SER' - smooth endoplasmic reticulum. Yes, the rough designation reflects the existence of endoplasmic bound ribosome entities/particles that are the main sites of cellular protein synthesis.
Protein synthesis
The protein structures that the rough er is dotted with are called ribosomes. If ribosomes are not present then it is called a smooth er.
Rough and smooth rough ER has ribosomes
Most of the proteins that are being synthesized come from the ribosomes attached to the rough endoplasmic reticulum (ER). After the protein synthesis is completed, the new protein molecule goes into the ER in order to complete their synthesis (sometimes it has to be passed through a process called "post-translational modification", e.g., the addition of a carbohydrate residue) that is taking place in the lumen of the ER. Afterwards, the complete protein (if it has to be secreted) goes to the Golgi apparatus and to the plasma membrane.
Rough and Smooth ER differentiated by the fact that "Rough" has ribosomes attached to its surface.The double membranes in both types (smooth and rough ER) form sacs called cisternae where protein molecules are made and collected.
