Plasma Membrane Flashcards
It is a semi permeable membrane that sorrounds the cytoplasma
Cell membrane
Name the two parts of a phopolipid bi layer
Nonpolar hydrophobic
Polar hydrophobic
These hydrophobic repels and stays on the inside of the cell membrane
These hydrophobic attracts and stays on the outside of the cell
Polar hydrophobic heads
Six molecules that let the cell membrane in
Sugars, proteins, fats, salts, oxygen and water
Four molecules that outs the cell membrane
Ammonia, salts, water and priteins
Cell membrane was discovered in the __ but it’s chemical conponent is on __
1890’s and 1915
Name two scientist who theorize that cell membrane are like stacks of sandwiches in 1935
Hugh Davson and James Daniell
He formulated the fluid mosaic model
Garth L. Nicolson
It is located on the main fabric of the membrane, the mostabundant lipid in jt
Phospolipids
It is tucked between the hydrophobic tails of the mebrane to dampen effect of temperature
Cholesterol
It is on the inner or outer surface of the phospolipid bilayer but not deeply embedded to ensure its cell recognition
Peripheral proteins
It is embedded in the phopolipid bilauer that may or may not be extend on both layers for transporation of substance through membrane
Integral proteins
