Discuss the difference in the solute concentration gradient and rate of diffusion between simple diffusion and facilitated diffusion.

1) You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described? 2) What are peripheral membrane proteins?

how can you increase the rate of facilitated diffusion across the plasma membrane?
