With the experimental conditions set at 10 mM glucose and 9 mM albumin, and the 200 MWCO membrane in place, which of the following is true?
  • The movement of a given solute usually occurs in both directions (into and out of the cell).
  • The solute directly requires ATP for its transport.
  • The net movement of water is toward the albumin.
  • Potassium is moved into the cell.
A cell is immersed in a beaker of solution. The cell membrane is permeable to water but impermeable to solutes. If the intracellular concentration is 10 mM and the solution is 20 mM, which of the following is true?
  • facilitated diffusion
  • vesicular transport
  • the potential energy of the solute
  • The cell will shrink.
Which of the following would result in NO change in osmotic pressure across a membrane? The solutes can diffuse through the pores and the concentration of solutes is the same on both sides of the membrane. Water is moving with its concentration gradient. The solutes can diffuse through the pores. The concentration of solutes is the same on both sides of the membrane.
  • The concentration of potassium is higher inside the cell.
  • The solutes can diffuse through the pores and the concentration of solutes is the same on both sides of the membrane.
  • Increasing the rate of filtration increased the concentration of solutes in the filtrate.
  • Both a membrane and a hydrostatic pressure gradient are required.
