Studies of glucose transport in liposomes have revealed that:a.
   glucose is transported against a concentration gradient.
  b. the binding of glucose triggers a conformational change in the carrier protein.
  c. the transport of solutes via carrier proteins is faster than via channel proteins.
  d. glucose phosphates move readily across the membrane by simple diffusion.
  e. glucose moves readily across the membrane by simple diffusion

Question 2

Although glucose molecules constantly diffuse into a cell along their concentration gradient,
  equilibrium is never reached and glucose continues to enter the cell. This is a direct result of:
  a. the very fast turnover rate of glucose metabolism.
  b. the continuous excretion of glucose from other parts of the cell.
  c. the rapid and continuous intracellular formation of glucose phosphates.
  d. the active transport of glucose.
  e. the ability of the cell to engulf glucose by pinocytosis.
