Transport across cell membrane

TRANSPORT ACROSS THE CELL MEMBRANE

CO2, O2, N ARE SOLUBLE IN THE CELL MEMBRANE IN THAT ORDER

AT REST 250 ML / MINUTE O2 INTAKE OCCURS
THE OUTPUT OF CO2 IS 200 ML / MINUTE

PARTIAL PRESSURE GRADIENT FOR O2 IS UPTO 60 mm Hg

PARTIAL PRESSURE GRADIENT FOR CO2 IS A FEW mm Hg

Other methods of transport:

Exocytosis
Endocytosis
Rafts and caveolae
Ion channels
Na, K ATPase
Transcytosis
