Multiple Choice Questions

Describe two variables that affect the rate of diffusion.
  • size of material and concentration of gradient
  • sodium chloride
  • the membrane the potential energy of the solute
  • the glucose diffused through the 200MWCO membrane, while there was no diffusion of albumin.
For solutes that move by simple diffusion, which of the following does NOT affect the rate of simple diffusion across a membrane?Check all that apply.the membrane pore sizethe potential energy of the solutethe size of the solutethe concentration of the solute
  • the membrane the potential energy of the solute
  • because urea was too big to pass through the 20 MWCO membrane
  • the glucose diffused through the 200MWCO membrane, while there was no diffusion of albumin.
  • size of material and concentration of gradient
Put the following in order from smallest to largest molecular weight: glucose, sodium chloride, albumin, and urea.
  • because urea was too big to pass through the 20 MWCO membrane
  • equilibrium
  • sodium chloride, urea, glucose, albumin
  • sodium chloride
Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction?
  • size of material and concentration of gradient
  • the membrane the potential energy of the solute
  • because urea was too big to pass through the 20 MWCO membrane
  • the glucose diffused through the 200MWCO membrane, while there was no diffusion of albumin.
