During an investigation on membrane transport, a researcher
exposed bacterial cells to different concentrations of two
different solutes: A and B. The rate of transport of each
solute into cells is represented in the graph.
= Solute A
= Solute B
Solute Concentration
Which of the following best explains the greater rate of
transport for solute A than for solute B at higher solute
concentrations?
Solute A is being transported by simple
diffusion, which does not rely on membrane
proteins to control the rate of transport.
A
Solute A is being transported by active
transport, which uses ATP and has higher
rates of transport than passive transport.
B
Solute A is being transported by facilitated
diffusion, which uses membrane proteins to
increase the rate of transport.
