3. Salivary amylase is an enzyme present in saliva that breaks down starch to maltose. Its optimum pH is 6-7 (around 6.9). The pH range for salivary amylase is 5-9. Thus, they are most active near neural pH.
Arginases are enzymes that are active at alkaline pH. Their pH range is 6-12, with an optimum pH of 9.5. Arginase hydrolyzes arginine in water to form ornithine and urea and is the final enzyme in urea cycle.
Pepsin is an enzyme active in stomach and is active at low pH. It breaks down protein to peptides. Its optimum pH is 1.5-2. It is active at a pH range between 1-4.
Right choice: pepsin

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....

Question 3 A Amylase is a protein that catalyzes the conversion of starch to simple sugars. Amylase activity in an aqueous solution can be measured by using iodine as a starch indicator. A solution containing iodine and starch will have a dark blue color, whereas a solution containing iodine but no starch will have a light brown color. The color change of an iodine solution from dark blue to light brown can be used to measure the rate at which...
