A portion of a plant cell is shown below, complete with a nucleus, cell membrane, and carrier
protein (green). Examine the green carrier protein and please choose the more specific
characterization from the choices shown. - ANS Symport carrier protein


The green carrier protein has been signaled to assimilate a phosphate (H2PO4-) ion. To do so, it
will most likely engage in which type of diffusion or transport? - ANS Facilitated Diffusion


The green carrier protein (shown in the figure below) will most likely co-transport which ion to
facilitate uptake of the desired phosphate (H2PO4-) ion? - ANS H+


Do the two steps shown above illustrate plant nutrient uptake (a.k.a. assimilation) by a carrier
protein? - ANS Yes


The green carrier protein has assimilated two phosphate ions, yet is being signalled to absorb as
many as possible. Will it continue to use the hydrogen ions (H+) as cotransport cations for
passive uptake of the desired phosphate ion? - ANS No, it will use sodium (Na+)
