I need to know the description+function of rough endoplasmic Reticulum and smoothe endoplasmic Reticulum.?

endoplasmic reticulum is a system of membranes forming a network of connecting sacs and canals that wind basck and forth through a cell's cytoplasm. rough er is where ribosomes drop their protein. smooth er manufatures fats, carbs, and protein. smooth er makes new membrane

There is no simple way of explaining it.\n\nThe electron transport chain is any series of protein complexes and lipid-soluble messengers that convert the reductive potential of energized electrons into a cross-membrane proton gradient. \n\nAnything less then that doesn't really explain what it is or does.

Facilitated diffusion (or transport) is the diffusion across a membrane which is aided by a membrane protein usually by a channel or pore this allows molecules that cannot pass through the lipid bilayer to enter the cell. The process still occurs down a concentration gradient, like normal diffusion and it requires no energy unlike active transport. For more information you could try looking up passive transport.\n\nI hope this helps

Hmm, you might want to double-check these answers, but:\n\nThe rough ER: "Many types of specialized cells secrete proteins produced by ribosomes attached to rough ER" i.e. insulin. The rough ER also is a "membrane factory for the cell", "adding membrane proteins and phospholipids to its own membrane".\n\nThe smooth ER: Processes include "the synthesis of lipids, metabolism of carbohydrates, and the detoxification of drugs and poisons". When you have a lot of smooth ER, your tolerance for drugs and alcohol builds up because your body can detoxify itself faster.\n\nMicrovilli increase the rate of nutrient reabsorption into the bloodstream.\n\nGolgi apparatus: Controls secretion, modifies proteins from the rough ER, helps transport lipids around the cell, and helps make lysosomes, makes sure plasma membrane proteins get where they need to be

The plasma membrane or the cell membrane is semi-permeable.Its function is to regulate the exchange of materials between the cytoplasm and extracellular fluid.

Endocytosis is when things move into the cell, and exocytosis is when things leave the cell.  Both processes involve vesicular transport, either clathrin coated vesicles or caveolae.  For endocytosis, the cargo binds to a receptor on the membrane, which either causes the formation of a clathrin coated vesicle or a caveolae.  The vesicle then moves into the cell.  With exocytosis, the vesicle is formed from the ER or golgi, then moves out to the membrane.

A post office of a cell.\n\nGolgi Apparatus actually sends information to different parts of the cell.

reticulum, that's how its spelled...and it's the network of transportation through a cell

Rough Endoplasmic Reticulum (ER) has ribosomes on it while smooth ER does not.\n  The reason it was named ROUGH ER is because it looks all bumpy ("rough") when viewed under a microscope (the bumps are the ribosomes).

Endoplamsic reticulum (ER) is explained above.\nExamples of reticuloendothelial systems are the Liver and the Spleen. On microscopic examination, these organs show a strange structural organization. Cells form extensive hollow cannals that allow blood to pass through. You may describe it as sinusoidal. These cannals act like blood vessels but are not blood vessels.

http://en.wikipedia.org/wiki/Golgi_complex\n\nThe primary function of the Golgi apparatus is to process and package macromolecules synethesised by the cell, primarily proteins and lipids. The Golgi apparatus forms a part of the endomembrane system present in eukaryotic cells.

Nuclear membrane is formed by a series of  flattened cistenae aligned sideways with gaps called nuclear pores. There are pore complexes guarding the nuclear pores.The flattened cisternae are smooth- surfaced endoplasmic reticulum. It is a typical biological membrane of lipo-protein.\nPlasma membrane is glyco-lipoprotein complex.The overcoat of the plasma membrane is made by the Golgi Complex. It is a complex of carbohydrate side chains along with proteins.The overcoat lies over the bilayer of lipid through with proteins lie across: some  projected,  others buried in the bilayer of lipid. Plasma membrane contains several enzymes and channels connected with transport of ions and small molecular weight substances.

Yes, it is C, pardner.\n\nHelps cell to continually turn over intracellular proteins before they get too old or nonfunctional. Breaks them up into lttle pieces. On the macro level, keeps you looking like yourself instead of slowly fading away.\n\n"Lysosomes contain various hydrolytic enzymes that are capable of digesting nucleic acids, polysaccharides, fats and proteins. The inside of a lysosome is acidic."\nhttp://biology.about.com/library/weekly/...\n\n2004 Nobel Prize:\n"Proteasomes are complex structures inside cells that break down proteins. Ubiquitin proteasome system is a barrel-shaped multi-protein complex that can specifically digest other proteins into short polypeptides and amiino acids in an ATP-driven reaction."\nhttp://en.wikipedia.org/wiki/proteasome...\n\n\nHere is a good site for checking out things in this subject area. It is a wonderful biology site.\n\nhttp://users.rcn.com/jkimball.ma.ultrane...\n\nThe Golgi apparatus functions in transporting materials out of the cell. \n\nDon't forget to pull up the urls and read more.

Goblet cells are glandular simple columnar epithelial cells whose sole function is to secrete mucus.\n\nThe majority of the cell's cytoplasm is occupied by mucinogen granules, except at the bottom. Rough endoplasmic reticulum, mitochondria, the nucleus, and other organelles are concentrated in the basal portion. The apical plasma membrane projects microvilli to increase surface area for secretion.

here's a basic answer about stuff we were recently talkin' about in class.... there are intrinsic and extrinsic proteins... also called integral and peripheral proteins... the first guys completely span the membrane bilayer and the second guys just touch the surface of the membrane or only partially go into it.  Proteins can diffuse laterally in the membrane.  They also decrease the fluidity of the membrane and increase its rigidity.  I believe it's oligosaccarides or carbohydrates can also bind to the proteins.  Most of the proteins function though as transporters.  There's so many transporters that that's a new questions in itself and i don't feel like the typing! ;)

A membrane-bound organelle in the cytoplasm of most cells containing various hydrolytic enzymes that function in intracellular digestion\nBasically it helps brake down complex molecules into smaller, simpler ones

No. \nFirst of all, the endoplasmic reticulum is contained by the cells( except neuronal ones). It's job inside the cell is in the protein metabolic reactions.\nThe microsom is a genetica structure, much smaller than any other components of the cell. It helps transporting genetical information from the reticulum to other structures with the help of genes.
