Mechanism of
passive transport: passive transport
can continue to occurs if the absorbed solute is immobilised . Cations have tendency to
move from electropositive to electronegative side while anions have tendency to
move from electronegative to electropositive side.
There are two mode of active transport :
i.Lipid matrix
permeability: - lipid soluble
substances can pass from the semi permeable membrane according to their
solubility and concentration gradient
ii. Hydrophilic membrane
channel: - these are the channels which are formed by
tunnel proteins, channels makes the membrane semipermeability so water can pass
outside and inside according their osmotic gradient , co2and o2 also can
diffuse from through these channels as per their conc. Gradient .
