A chemiosmotic model
has been proposed to explain
Polar transport , following steps are involve in the transport of auxin
polarly;
a) IAA enters the cell either passively in the undissociated
form (IAAH) or by secondary active cotransport in the anionic form (IAA–)
b) The cell wall is maintained at an acidic pH by the
activity of the plasma membrane H+- ATPase
c) In the cytosol, which has acidic pH, the IAAH form
predominates
d) The anions exit the cell via auxin anion efflux carriers
that are concentrated at the basal ends of each cell in the longitudinal
pathway
Which of the following is the correct statements about the polarly transporting of auxin?
