Question

explain what a extracellular buffer system?

Answer 1

Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. They could be extracellular or intracellular. Extracellular buffer systems are those buffer systems, either naturally occurring or synthetic, which provide an environment outside of living cells. Extracellular buffers include bicarbonate and ammonia, whereas proteins and phosphates act as intracellular buffers.The major buffer system in the ECF is the CO2-bicarbonate buffer system. This is responsible for about 80% of extracellular buffering. This buffer consists of weak acid like carbonic acid and conjugated base like bicarbonate ion..
