Lecturer’s name: Mr. Paul Davidson Discussion The name of enzyme involved in this experiment is salivary amylase‚ which presents in our saliva. Salivary amylase catalyses the breakdown of complex sugar‚ such as starch‚ into a simple sugar‚ such as glucose. In this experiment‚ the optimum temperature for salivary amylase to function is 37˚C. Above the optimum temperature‚ the kinetic energy in the substrate and enzyme increases. The number of collisions between

digestive process in the mouth. Salivary amylase is created by by three large salivary glands. This amylase breaks down starch and carbohydrates. However‚ since only a few people keep the food in their mouth long enough for the amylase to digest the carbohydrates completely‚ it continues down to the stomach through the esophagus. A lot of people may think that the salivary amylase continues working on the carbohydrate. However since the stomach’s acidity is very high the salivary enzyme is inactivated. Carbohydrates

12 Experiment No. 12 Aim- To study the effects of temperature on the enzymatic activity of salivary amylase on substrates starch. Materials required- Test tubes‚ beakers‚ pipettes‚ funnels‚ thermometer‚ cotton‚ starch‚ iodine‚ potassium iodide‚ sodium chloride‚ thermocol box‚ buffer solution of pH 6.8 & match box. Principle- Salivary amylase is an amylolytic enzyme found in saliva released from salivary glands. All the enzymes show optimum enzymatic activity around 37° C which is our body temperature

Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? 7.0 Why? because that is when the salivary is most effective and it breaks down carbohydrates 2. How do you know that the amylase did not have any contaminating maltose? because the sample didn’t change color. Negative sugar/IKI test. No change from original blue bright color. We used a negative control to see if there is any amylase in the maltose 3. What effect

Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing
