話説兼職芒果在這67 天以來，向大家分享了一些化學和經濟的知識，但其實兼職芒果也是一個有讀生物的芒果，而且後天就要小考了。今天想爲分享 cell membrane!
Cell membrane30Please respect copyright.ＰＥＮＡＮＡ4U7Uh8ajc7
all cells whether they are prokaryotic or eukaryotic have a cell membrane30Please respect copyright.ＰＥＮＡＮＡWcZXjfwaM8
components: phospholipid and proteins 30Please respect copyright.ＰＥＮＡＮＡUjD2evEGYW
structure : phospholipid are arranged in a bilayer 30Please respect copyright.ＰＥＮＡＮＡahFtoBLjet
with the hydrophobic head point outwards and the hydrophobic tails pointing towards the centre of the phospholipid bilayer
the characteristics of cell membrane are as follows :
1. fluid nature 30Please respect copyright.ＰＥＮＡＮＡ20KXXGWNr3
phospholipid and proteins are able to move laterally 30Please respect copyright.ＰＥＮＡＮＡroUTEjfKXa
2. mosaic pattern 30Please respect copyright.ＰＥＮＡＮＡBPfNE1AbNy
protein are embedded or interspersed in the phospholipid bilayer 30Please respect copyright.ＰＥＮＡＮＡU33ZkSlrsC
3. asymmetric pattern 30Please respect copyright.ＰＥＮＡＮＡmlekLs4OmL
composition and orientation of protein are different with respect to two sides of the bilayer.
*Glycoproteins (protein with saccharides attached) are only found on the external surface)
