CELL STRUCTURE Flashcards
animal cell contains
protoplasm , cell membrane
protoplasm contains
nucleus , cytoplasm
cytoplasm contains
cell organelles , cytosol , cytoskeleton , non living materials .
The fluid between the nucleus and surface membrane
cytoplasm
controls the flow of substance into or out of the cell
“ selectively permeable “
cell membrane
controls the communication between the cell and other ones
cell membrane
gives a shape to the cell
cell membrane
sandwich theory , fluid mosaic theory
cell membrane theory
Phospholipids , cholesterol , proteins .
structure of the cell membrane in the fluid mosaic model
polar hydrophilic head with non polar hydrophobic tail
phospholipids
hydrophobic area , helping the bilayer to stay fluid flexible stable .
cholesterol
carbs with fats
glycolipids
carbs with protein
glycoprotein
98% lipids
structure of cell membrane in fluid mosaic model
75% phospholipids ( bilayer )
structure of cell membrane in fluid mosaic model
3% glycolipids
structure of cell membrane in fluid mosaic model
20% cholesterol
structure of cell membrane in fluid mosaic model
2% protein
structure of cell membrane in fluid mosaic model
integral protein , peripheral protein
parts of the 2% protein in the bilayer
Transmembrane proteins , Integral monotopic proteins
parts of the integral proteins
this protein break through the membrane and extend outside one side of the membrane
Integral monotopic proteins
extends into the membrane and penetrates it to the other side of the membrane
Transmembrane proteins
It is a protein that binds to the inner surface of the membrane
peripheral protein
glycolipids with glycoproteins
Glycocalyx
