effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests starch into di- and monosaccharides. Since it’s a salivary amylase‚ the enzyme works best at an alkaline pH of 7‚ in other words‚ the optimum pH is 7. At this pH‚ the rate of amylase activity will be at it’s highest. A

Digestion can occur naturally at body temperature‚ however this process takes a very long time as it happens at such a slow rate. For digestion to increase in these circumstances‚ body temperature would have to increase as well. However this is not possible as it would interfere with other body functions.This is why enzymes are vital as they speed up this process by lowering the activation energy required for the reaction to occur and they do so at body temperature. Summary: 3. Enzymes break down

The optimum temperature for enzymes is 40 degrees but anywhere above that temperature the enzymes activity rapidly decreases because the enzymes denatures. Enzyme optimum pH This graph compares

The Effects of Temperature on the Action of Diastase on a Starch Suspension Hypothesis: The practical being carried out is to observe the effects of temperature on starch break down using a synthesized version of salivary amylase‚ this being Diastase. The starch will be placed into the Diastase and water and then placed in baths of water of different l. temperatures. The test tube containing water will have little or no reaction at all. However‚ the test tube containing the Diastase
