Questions and tables from experiment three1. What is the optimal pH for salivary amylase activity, and how does it compare to the pH at which the enzyme is normally found? • The optimal pH level for salivary amylase is approximately 6.8. Any change in pH below or above the optimal pH decreases the rate of action of the enzyme. Changes in pH can lead to changes in the ionization state of the substrate or the enzyme or both. The optimal pH level is slightly acidic while the enzyme is a little more basic.2. The pH in the stomach of most animals is usually between 3 and 4. How much dietary starch is likely to be converted to maltose in the stomach compared to the mouth and esophagus?• I believe the level of dietary starch converted to maltose compared to the mouth and esophagus vary from person to person. It will vary due to the fact that each individual will have different pH levels in their body3. What is the optimal temperature for salivary amylase activity, and how does it compare to the temperature at which the enzyme normally acts? • I believe the optimal temperature for salivary amylase activity would be 37 degrees Celsius or 98.6 degrees Fahrenheit. The reason I believe this is because the human body operates at a temperature of approximately 98.6 degrees. If there is too much salivary amylase relative to the starch solution, then it may break down much faster than it should or it may overwhelm the body. solution and cause an inaccurate result. The same if there was not enough salivary solution compared to the starch solution. Results may take longer to appear if the starch solution is excessive. Another thing to consider is the concentration of the starch solution. If the concentration of the solution is too concentrated, it may not be accurate
