MEMBRANE, transport protein - Coggle Diagram
MEMBRANE
Fluidity of Membranes
movement of lipids
rotational
flip-flop
letral
length of fatty acyl tails ( shorter -more fluidity)
double bonds ( unsaturated- more fluidity)
cholesterol with high conc. ( low T , more Fluidity )
STRUCTURE : CONSIST OF
proteins
Peripheral or extrinsic membrane proteins
Integral or intrinsic membrane proteins
lipid anchored protein
transmembrane proteins
a lot of phospholipids or phospholipid bilayer
Synthesis of Lipids in smooth (ER) and Transported via vesicles to Golgi, lysosomes, vacuoles, or plasma membrane
carbohydrates
Ways to move across membranes
Active transport : Requires energy – up or against gradient
passive transport : Requires no input of energy – down or with gradient
Facilitated diffusion – Diffusion of a solute through a membrane with the aid of a transport protein
Passive diffusion – Diffusion of a solute through a membrane without transport protein
transport protein
channels
Transporters
