Question
TABLE TWO REACTION RATE VERSUS pH PH intenaity of eolor + 2 + + + 1. -les Does the data suggest there is an optimal pH for enzyme activity? Ifyes, what is that pH? Why didn't the enzyme function equally well at all pH's? 2. 3. What do you think the normal pH within the turnip cells might be? 4. Enzymes which function in the plasma of your blood would work best in what pH range? 1-35-7.49S Based on the lab results, why is it important for human beings to maintain the pH of their body fluids within a narrow suitable range? 5.Explanation / Answer
2) Enzymes are proteins (almost all) and proteins are made up of amino acids and these amino acids can be basic or acidic in nature depending on their functional groups on their side chain. Now, the 3-D shape of a functional enzyme is maintained through the ionic bonds between these amino acids. Each enzyme/protein will have an optimum pH at which an equilibrium state of ionization is maintained and any significant fluctuations in pH will cause the 3D structure to be altered and as a result of that the active sites for the enzyme might become inaccessible to the substrate or the enzyme itself may get denatured because of which the functionality of the enzyme will be less. Hence the enzyme did not function equally well at all pHs.
Suggested short Answer: Change in optimal pH will cause the enzyme to denature or make its active sites inaccessible to substrates and hence will not function normally.
3) The acid-base indicator used in the exp changes its intensity at the pH of around 5 Based on your data). So the normal pH would be around 5-6
5) As explained in answer 2 and as seen in the data in your table, the enzymes and proteins in our body will get denatured or lose its function at any pH which is not it's optimal pH. This holds good for all the biomolecules in our body including body fluids like blood. Blood contains all sorts of molecules like proteins involved in homeostasis, immune response cells, blood cells, neurotransmitters so on which all work under the ideal pH provided by the blood. So, if the blood pH deviates from its range of 7.35 to 7.45, the biomolecules inside the blood will start to lose its function, be it waste elimination, signal transmission for homeostasis or maintaining immune vigil and can cause serious problems to our body including death.
