:(...helllpppppppppp please?

Question

i need some basic facts on the'Rough Endoplasmic Reticulum' at leat 6 basic facts about it,i tried the web but it all seems to detailed any suggestions
Thanxskyou foir taking your time
Very appreciated :)

Answer 1

1) The surface is studded with ribosomes that manufacture protein
2) Its membrane is contiguous with the outer layer of the nuclear envelope
3) It produces various substances including lysosomal enzymes and various proteins

4)

Erm.. .That's all I got

Answer 2

Here's what I came up with: Attached to the nuclear membrane is an elongated membranous sac called the endoplasmic reticulum. This organelle tunnels through the cytoplasm, folding back and forth on itself to form a series of membranous stacks. Endoplasmic reticulum takes two forms: rough and smooth. Rough endoplasmic reticulum (RER) is so called because it appears bumpy under a microscope. The bumps are actually thousands of ribosomes attached to the membrane’s surface. The ribosomes in eukaryotic cells have the same function as those in prokaryotic cells, protein synthesis, but they differ slightly in structure. Eukaryote ribosomes bound to the endoplasmic reticulum help assemble proteins that typically are exported from the cell. The ribosomes work with other molecules to link amino acids to partially completed proteins. These incomplete proteins then travel to the inner chamber of the endoplasmic reticulum, where chemical modifications, such as the addition of a sugar, are carried out. Chemical modifications of lipids are also carried out in the endoplasmic reticulum.

The endoplasmic reticulum and its bound ribosomes are particularly dense in cells that produce many proteins for export, such as the white blood cells of the immune system, which produce and secrete antibodies. Some ribosomes that manufacture proteins are not attached to the endoplasmic reticulum. These so-called free ribosomes are dispersed in the cytoplasm and typically make proteins, many of them enzymes, that remain in the cell.

Answer 3

sorry dont know a thing about what you are asking.
