plasma membrane Flashcards
phospholipids
- hydrophilic phosphate contained ( polar ) and a fatty acid hydrophobic tail ( non polar )
- a layer ( two layers ) of phospholipids becomes a phospholipid bilayer.
- has a fluid structure
hydrophobic
repels water
hydrophillic
attracts water
integral proteins
a permanent part of the membrane
transmembrane proteins
an integral protein that spans both of the of the phospholipid layers
peripheral proteins
a temporary part of the membrane and bind to integral proteins
intrinsic proteins
span the whole width of the membrane
extrinsic proteins
either or on the inner or outer part of the membrane
glycoprotein
a protein with a carbohydrate strand attached to it.
carbohydrates
recognises the difference between cells and antibodies
cholesterol
a lipid that gives stability to the membrane
partially permeable membrane
controls what exists and enters the cell
channel proteins
dont bind with molecules being transported involved in the passage of polar particles like ions.
carrier proteins
bind to molecules being transported so the shape of the molecule changes such as larger molecules like glucose. so much things through the membrane
plasma membrane
made of proteins and lipids ( phospholipids )
