Amylase break down starch into maltose. So the substrate of the enzyme is starch. More specifically it is two compounds amylose and amylopectin which is found in starch.
Active site is the region of enzyme where substrate bind and undergo chemical reaction.
Since the body temperature is 37 0C, the maximum optimum temperature for the amylase activity is 37 0C. Optimum temperature range is 35 to 37 0C
Optimum pH range of amylase is 6.7–7. The normal pH range for saliva is 6.2 to 7.6. Amylase will function in this range.
Add Answer to:
enzyme concentration decreases. Amylase is an enzyme that is produced in human salivary glands and secreted...

1) Based on the explanation on the interaction between starch, salivary amylase and iodine solution at the beginning of the presentation, please give a brief explanation on the differences in colour over time for each concentration. 2) Why do you think the rate of reaction increases as the concentration of the enzyme is increased? Is the rate of reaction increasing indefinitely as the concentration increases? 3) Why do you think the reaction rate is different as the pH of the...

Enzymes Temperature is an important factor that can regulate enzyme-mediated functions. Temperature is one of the tightly homeostatically controlled variables in the human body. What are the symptoms of loss of temperature control during a high fever? Explain why these symptoms occur based on enzyme function and cell signaling effects that are dependent on temperature. Based on Figure 1, explain how the temperature optimum of the activity of enzymes is expected to differ in organisms depending on where they live....

Each day, the pancreas produces up to 1.5 L of pancreatic juices that enter the duodenum via the pancreatic duct. The pancreatic juices consist of water, salts, bicarbonate ions, and digestive enzymes. Bicarbonate ion raises the pH of the acidic chyme from the stomach, stopping the active ity of pepsin and allowing the pancreatic and intestinal enzymes to function. The various pancre. atic enzymes and their substrates are listed in Table 10.2. Table 10.2 Various enzymes produced by the pancreas...
