HomeWork HELP!

Post by Stalkerfishy » Sat Dec 13, 2008 12:12 am

Ok, well there were about 75 questions I had to do. I've done most, but have alot of blanks. I've checked the internet and my book. But still nothing.
It would be great if you could help me :wink:

About the cell.

Answer as many as you can, please.

-Membrane enclosed region in a cell

-A network of microtubules, microfilaments and intermediate filaments

-A small membranous bag

-A cluster of protein-synthesizing organelles

-A water-soluble small basic protein often associated with nucleic acids

-Nonliving, outside cell membrane

-_______ membrane (starts with p, 6 letters)

- Commonest protein in muscles

- An intramembranous protein that binds to a substance being transported

- Where raw materials of ribosomes are made

-Structures on the cell membrane that are composed of simple sugars and amino acids

-Structure from which a chromosomal microtubule arises

- Composed of glycerol and fatty acids (Ends in D, 5 letters)

- Structure composed of phospholipids

-network of DNA and histones

-Site of final precessing of membrane proteins, proteins and polysaccharides for export

- A thin skin or membranous coating

If your text book doesn't answer those questions you've got the wrong text book..


Basic Cellular structure
Eukaryotic nucleus
Intracellular transport
Cellular membranous structures

[PS:Most common protein(s) in muscles are actin, myosin, and desmosome junctions.]

The structure composed of phospholipids is the phospholipid bilayer, which has integral proteins, periphery proteins, sphingolipids (which form the lipid rafts), among many other things.

There's one for you, but I agree with keenangp, your text book should definitely cover those topics, and Google is a good start to answer your questions, just make sure the source is reliable.
