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 membrane169Please respect copyright.ＰＥＮＡＮＡV64itwtz0u
all cells whether they are prokaryotic or eukaryotic have a cell membrane169Please respect copyright.ＰＥＮＡＮＡ7Ct7K6W4Ha
components: phospholipid and proteins 169Please respect copyright.ＰＥＮＡＮＡH4xaGjiAwv
structure : phospholipid are arranged in a bilayer 169Please respect copyright.ＰＥＮＡＮＡ4emWJf5u1b
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 169Please respect copyright.ＰＥＮＡＮＡ4ha7fkYI4W
phospholipid and proteins are able to move laterally 169Please respect copyright.ＰＥＮＡＮＡUIdYOSXVNT
2. mosaic pattern 169Please respect copyright.ＰＥＮＡＮＡ1UxnuNNhMO
protein are embedded or interspersed in the phospholipid bilayer 169Please respect copyright.ＰＥＮＡＮＡpLNC5GDdQJ
3. asymmetric pattern 169Please respect copyright.ＰＥＮＡＮＡXXzLJATprU
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)
