Transportation through the cell membrane - Coggle Diagram
Transportation through the cell membrane
Active
Totally buried intrinsic protein
a.k.a PUMP
uses energy(ATP) for transport
Against concentration gradient low-->high
Example:-
Na+ & K+ pump
Uphill transport
Passive
Simple Diffusion
Neutral solute
Non polar substances
Gases
Osmosis
Diffusion of water
Exosmosis
Water moving from outside->inside
Endosmosis
Water moving from inside->outside
Facillitated transport
Charged particles(+ &- ions)
Hydrophilic nature
Polar nature
Since they are hydrophilic and polar they
Cannot pass through the non-polar lipid layer
They require
carrier proteins & Channels
TB IP/Transmembrane protein
No energy used
Acc. to concentration gradient high-->low
Downhill transport
Bulk transport
Transport of proteins, lipids, hormones, enzymes
Endocytosis
Pinocytosis(cell drinking)
real life example
Phagocytosis(cell eating)
Real life example
Exocytosis(cell vomiting)
Real life example
Membrane forms
Vesicles
