A researcher is studying ion uptake in plant roots using radioactive tracers. They observe that metabolic inhibitors significantly reduce the uptake of potassium ions, but not the uptake of chloride ions. What can be inferred about the uptake mechanisms of these two ions?
Potassium uptake is primarily active, while chloride uptake may be passive or facilitated.
Both potassium and chloride uptake are primarily active processes.
Both potassium and chloride uptake are primarily passive processes.
Chloride uptake is primarily active, while potassium uptake may be passive or facilitated.
