Skeletal Muscle Cell With Depleted ATP Stores Ion transporter Cytosolic K+ Cytosolic Na+ Cytosolic Ca2+ NKA NCX SERCA1:58 l 5GE Done 11 of 23 3 of 12 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. Submit !!
