cell membrane---please help me...---
What kind of molecules make up the majority of the cell's membrane?
Can anyone help me?
Can anyone help me?
Keep in mind that when you see those diagrams of balls and sticks, those represent the carbon backbone of fairly large molecules that themselves take up space. How much actual space is between the molecules would be determined by the chemical interactions and how tight those molecules can be packed. Transmembrane proteins can span across the entire bilayer, and other membrane-bound proteins or other molecules will have their more hydrophobic domains stuck inside the bilayer.Artermis said:Maybe a strange question
but is there ANYTHING in-between the phospholipid bilayer itself? as in between the space where the two heads are... where all the tails are crammed together and the proteins are integrated into the cell membrane. cholestrol? or is all that space inbetween the bilayer taken up by the tails and proteins?
The intercellular space is the space between cells, not the space inside the membrane.yomamma said:The tails are hydrocarbons and fatty acids. That little space is called 'intercellular space' and the only things that might go in there are cholesterols and transmembrane proteins.
Hey, no problem, that's what we're here for.yomamma said:whoops. got a lot more to learn.![]()
