Here's a recap:
I'm basically the gatekeeper of the cell
I'm double-layered and embedded with proteins
I carry markers that allow cells to recognize one another and can transmit signals to other cells
What can I say... I do a lot of great things. #OrganelleWars@lmartinezchinn
Here's a little poem:
My ionic balance
So badly deranged
My freedom, nonchalance
Themselves have hanged.
Time I evolve, take action
And get rid of me vain
Time I start selective absorption
Surround self with plasma membrane.
#OrganelleWars@lmartinezchinn
What will be the percentage of carbohydrates, proteins and lipids in the plasma membrane. This proportion varies among various types of cells. In case of typical human cells, the ratio of protein:lipids:carbohydrates is 50:40:10. Now that's a lot... #OrganelleWars@lmartinezchinn
The fluid mosaic model also describes how nutrients are transported into and out of the cell: describing the passive and active ways of transport. #OrganelleWars@lmartinezchinn
Another Fun Fact: During cell division, I fold and pinch off to create two new cells, each surrounded by part of the same original membrane. I know... pretty cool right. ๐#OrganelleWars@lmartinezchinn
I offer two ways for materials to enter and leave the cell, diffusion and active transport. Diffusion is where they naturally move to reach equilibrium. Active transport is where they use energy to move. #OrganelleWars@lmartinezchinn
Not only do I protect it, but I mediate cellular processes by regulating the materials that enter and exit the cell & carry markers that allow cells to recognize one another and can transmit signals to other cells via receptors. ๐ #OrganelleWars@lmartinezchinn
Fun Fact: I have so many kinds of molecules in cell membranes that scientists describe their understanding of the membrane as the "fluid mosaic model" of membrane structure. Here's an example down below: #OrganelleWars@lmartinezchinn
@smootherERthanU You really hate to see it don't you. Your friend @RoughEndoRec is doing a better job of stating his case, but how about you tell me why you are relevant to the cell because I see no need for two Endoplasmic Reticulum.
