In biological systems, chemical buffers prevent sharp and sudden changes in pH.
- In biology, homeostasis refers to stable conditions required for the survival of organisms.
- The pH is a scale used to determine how acidic/basic water is. The pH range from 0 to 14 ( a pH equal to 7 is neutral).
- In human blood normal pH is about 7.35 to 7.45.
- A sudden change in this value alters and negatively affects the homeostasis of the body.
- The carbonic acid-bicarbonate is the most important chemical buffer which is used for mantaining acid-base balance (homeostasis) in the blood.
- The blood pH can change due to respiratory acidosis/alkalosis and metabolic acidosis/alkalosis.
In conclusion, chemical buffers prevent sharp and sudden changes in pH.
