Active Solute Transport across Frog

Solute Transport Plant Plasma Membrane

The plasma membrane proton pump (H+-ATPase) energizes solute uptake by secondary transporters. Wild-type Arabidopsis plasma membrane H+-ATPase (AHA2) and truncated H+-ATPases lacking 38, 51, 61, 66, 77, 92, 96, and 104 C-terminal amino acids were produced in yeast. All AHAS species were correctly targeted to the yeast plasma membrane and, in addition, accumulated in interna1 membranes. Removal ...

Fractal mobile/immobile solute transport

[1] A fractal mobile/immobile model for solute transport assumes power law waiting times in the immobile zone, leading to a fractional time derivative in the model equations. The equations are equivalent to previous models of mobile/immobile transport with power law memory functions and are the limiting equations that govern continuous time random walks with heavy tailed random waiting times. T...

Extraction of model parameters for reactive solute transport

In the present study, tried to examine the reactive solute relationships for transport and degradation processes through the rockfill media. By applying the analytical solution of reactive transport, the 1st to 3rd theoretical temporal moments have been extracted then, by using two methods of curve fitting and temporal moment matching, the coefficients of dispersion and degradation have been ex...
