the opinion that dhpa is transported into the cell by facilitated diffusion , is supported 1 ) by the data on dhpa transport as a function of temperature and extracellular concentration , 2 ) by evidence of countertransport , 3 ) by temperature-dependent exit of dhpa , 4 ) by specific inhibition of dhpa transport in the presence of adenosine and deoxyadenosine and 5 ) by the fact that intracellular concentration of dhpa in equilibrium does not reach the concentration of dhpa in the medium .
