Which molecule is found in animal cell membranes only? cholesterol, phospholipids, proteins or carbohydrates.
00:09
So this has to be compared to other cell membranes, and all organisms have cell membranes, and they have a lot in common.
00:17
For example, they are all made up of phospholipids.
00:20
So all membranes have a phospholipid bilayer.
00:27
I'll put cell membranes, just to be safe.
00:29
All cell membranes have a phospholipid bilayer.
00:32
They are all containing proteins because the proteins work as channels, as receptors.
00:40
They're absolutely necessary to life.
00:44
So all use proteins.
00:46
Okay, and then carbohydrates.
00:49
So other cell membranes do have carbohydrates as well.
00:53
So many use lycoplypids.
00:57
So glycolipids are really good for cell to.
01:00
Cell communication, and other multicellular organisms use these as well.

It's not just us...
