I believe that the chemical buffers provide the shortest term mechanisms for preventing acid-base imbalances in the body. Chemical buffers normally act within a fraction of a second to resist a pH change. On the other hand the longest mechanism is the kidney system which ordinarily requires from several hours to a day or more to affect changes in blood pH.
The molecules doesn't need energy to cross through.
The diffusion doesn't need protien, the molecules pass between phospholipids by passes protien. It moves smaller molecules. Facilitated need protien also hormone, and larger molecules.
I wish it makes sense.
