What process takes place in the rough endoplasmic recticulum?

Answer 1

Ribosomes are found on an endoplasmic reticulum and those ribosomes create proteins that are inserted in the rough endoplasmic reticulum (ER) , where they may be chemically modified

Answer 2

• The process takes place in rough endoplasmic reticulum is
• Lysosomal enzymes with a mannose-6-phosphate marker added in the cis-Golgi network
• Secreted proteins, either secreted constitutively with no tag or secreted in a regulatory manner involving clathrin and paired basic amino acids in the signal peptide.
• Integral membrane proteins that stay embedded in the membrane as vesicles exit and bind to new membranes. Rab proteins are key in targeting the membrane; SNAP and SNARE proteins are key in the fusion event.
• Initial glycosylation as assembly continues. This is N-linked (O-linking occurs in the golgi).
  • N-linked glycosylation: If the protein is properly folded, glycosyltransferase recognizes the AA sequence NXS or NXT (with the S/T residue phosphorylated) and adds a 14-sugar backbone (2-N-acetylglucosamine, 9-branching mannose, and 3-glucose at the end) to the side-chain nitrogen of Asn.

Answer 3

The smooth endoplasmic reticulum of the small intestine make lipids from fatty acids and glycerol (lipid synthesis), this is then passed onto the Golgi apparatus for export.

The smooth endoplasmic reticulum can also make steriods.

Rough endoplasmic reticulum is concerned with the transport of proteins which are made by the ribosomes on its surface.

Answer 4

Protein synthesis occurs in the rough endoplasmic reticulum. This organelle is studded with ribosomes that help in the production of proteins which are then modified and transported to other parts of the cell.

Answer 5

the reaction of a cell that transports items

Answer 6

organelle in which components of the cell membrane are assembled and some proteins are modified

Answer 7

The rough endoplasmic reticulum is similar to an assembly line in a factory making proteins.

Answer 8

proteins
