How can “apparently” small changes in pH, produce significant biological effects? Cite an example of a biologi?

Having trouble answering this, i know that even though it is a small change, but the concentrations of H and OH change a lot? can anyone add to this and give an example. thanksHow can “apparently” small changes in pH, produce significant biological effects? Cite an example of a biologi?
Acidosis would be an example - results when pH of blood (normally 7.4) drops below 7.35.

Well, the relationship existing between pH and Living Tissues get evidence in the close range allowed to pH levels speaking about Physiological Conditions.

Indeed, there are very few Living Organisms able to move downward pH%26lt;4 or upward pH%26gt;10.

This recalls surely the HYDROLYTIC ACTIONs PLAYED BY STRONG ACIDIC OR BASIC MEDIA.





Moreover, Mathematics has been involved by chemists to calculate pH levels. Chemists defined



pH = -LOG(|H+|)



so YOU REMARK THAT pH IS A LOGARITHMICAL INDEX : SLIGHT CHANGE ON pH CAN'T RESULT LINERALY SMALL EFFECTS ONTO |H+|.



I hope this helps you.
