what factors will affect the rate of passive transport
Factors affecting rate are the amount of pressure and the size of pores in the filter. The substances needed for movement across blood vessels are water and small ions. Carrier-mediated Transport: Facilitated diffusion involves carrier molecules that passively transport solutes down a concentration gradient. Factors that affect rate are the amount of pressure, the size of pores in the filter, and the availability of carrier protein. The substances involved for all cells are glucose and amino acids.
