How does it affect the enzyme Activity?: The value of pH is from 1 to 14 and pH can be neutral,alkali or acidic.pH 7 shows that it is netural and any number higher than pH7 is alkaline and lower than pH7 is acidic.pH are concentration of hydrogen ions that are found in solution.However, there is more concentration of hydrogen ions (protons) in acidic solutions and they are known as proton donors.If we look at the strucutre of the enzymes especially tertiary strucutre you can find bonds such as hydrogen bond and lots of ionic , which gives the shape to the active site and helps to keep them in place properly. These enzyme are made out of amino acid and within them you can find oppositely charged group that are attracted to each other , which …show more content…

: pH can affect the amino acid and this is because amino acids that are made of many proteins chains can be affected by them as they react quickly with pH’s that are alkaline or acidic.Acidic , basic,polar or neutral are the type of R group which you can have.To help define these you hae to look at the strucutre and formula of these.The changes made to the amino acid can make a bad impact on the 3D strucutre of them as they will change. The pH of the solution can tell whether the chains of these can be ionized.For the carboxylic group of the amino acid if the pH is higher than the pka value of the carboxylic group of the amino acid , it will result in changes in the COOH group become deprotonated and changes into COO.Therefore, do not stays the same.However, if the pH was lower compared with the pKa value then there will be no changes and it will stay same. Other the other hand, the changes cause in the amino acids will cause changes in the finally shape of the enzyme’s active site.However, if you have a lower pH than the the pKa value of the amine group there will be changes as they become protonated and the NH2 change to NH3+ therefore, they do not stay same.But if you have pH , which is high than the pka value of the amine group of the amino acid then there will be no changes on the amine group (NH2) so, it stay
