Changes inpHandtemperatureaffectenzymatic activity. Any deviation from theoptimum pHlevel or an increase oftemperatureover theoptimumleveldenaturalizestheenzyme, and loses itscatalytic activity.----------------------------------Enzymes, like allproteins, arepolypeptidic molecules. They need to get an accuratetridimensional structureto accomplish theirfunction.There is a limited temperatureandpH levelat which they lose thatstructureanddenaturalize.•pH changesThe mostaccurate configurationfor the bestcatalytic performancedepends on thechargeof thelateral chainsand theenvironmental pH.Enzymeshaveionizable chemical groupsin thelateral chainsof theiramino acids.Depending on theenvironmental pH, these groups will have apositive,negative, orneutral charge.There is anoptimum pH levelat whichenzymesget thebest configurationto accomplish theirfunctions.Most enzymesare sensitive to anychange in pH, which might drasticallyaffect theiractivity.So everyenzymehas itsoptimum pH level, and any slightdeviationswill cause theenzyme denaturalization, hence, itsactivity loss.•Temperature changesIn general, the increase intemperatureaccelerateschemical reactions.For every 10ºC oftemperature increase, thereaction velocityduplicates.Theoptimum temperatureis the range in which theenzymeexpresses itshighest activity rate.⇒ When theenvironmental temperatureislowerthan theoptimum, there is aslow enzymatic activity.⇒ When thetemperatureexceedstheoptimum point, theenzymatic activitysharplydecreases. Itdenaturalizesthe enzyme. Over this level, thereaction velocityis counteracted by the loss of thecatalytic activitydue todenaturalization. Enzymatic activity decreases until it completely annulates.-------------------------------------------------Related link:brainly.com/question/1749392?referrer=searchResultsbrainly.com/question/3134846?referrer=searchResults...
