What is relationship between enzyme and pH?
pH is one of major factors that affect the enzyme. Enzymes only work in a specific pH. When a pH of that region is lower or higher than the required pH, it denatures and does not work. An example of this is amylase. Amylase is an enzyme inside a mouth that breaks down carbohydrates. The mouth is slightly basic, and that creates the perfect environment and the perfect pH that amylase works in. When amylase is taken down to the stomach where the pH is very acidic, amylase does not work anymore and the body has to rely on another enzyme that works in a more acidic environment to continue to break the food down.
What are the differences between fungal amylase and bacterial amylase?
Enzymes from an organism are generally going to work best around the conditions that the organism tends to live. Fungi usually live in quite cool areas (think woodland) and in acidic soils. Bacteria can live anywhere generally and their optimum conditions could be anything.
Where does amylase act in humans?
Amylase is produced by the salivary glands and works in the mouth to break down chardohydrates(digests starch into maltose). It only works for a short amount of time because when you swallow the food it is inhibated by the acid in the stomach. Amylase works best at a pH of 7.
What pH does amylase works best with?
Most human enzymes work at a optimal pH of 7.4, but other enzymes work at many different pH ranges, for example Pepsin works best at an optimal pH of 2.6 and Trypsin works best at an optimal pH of 7.8.

What is amylase associated with?
Amylase is an enzyme. Almost all enzymes end with -ase. This enzyme works on complex carbohydrates to simple carbohydrates like sugars.
What factors affect the activity of enzymes?
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
Does the enzymes act in the mouth or in the stomach?
Both. Salivary amylase works in your mouth, and the others in your stomach and duodenum.
The enzymes that digest dietary sugars are produced by the?
the small intestine. Pancreatic amylase, which is from the pancreas, enters the small intestine to digest the carbohydrates also, but the small intestine itself has many specific enzymes, including maltase, sucrase, and lactase. There is also an amylase from the saliva, which works in the mouth, but once the food (or bolus, now) enters the stomach, the salivary amylase stops working.

Where does Amylase work in the gut?
In the mouth, salivary amylase works to break down cooked starch into maltose. The duodenum (first part of the small intestine), pancreatic amylase works to do the same. Amylase only works in these places because they provide the optimum pH conditions for amylase to work (range from pH 6 - 8).

What temperature does amylase work best at?
Amylase works best at body temperature, which is around 37 degrees Celsius. This is because if the temperatre is too low, the amylase will collide slow as the kinetic energy will be low. It reacts fastest and best in this temperatue as lota of kinetic energy is given to the molecules and the particles therefore collide faster. Although, when the temperature is too high, the enzymes (amylase) gets denatured which means that they loose their shape. This way they do not react.
What is meant by the statement enzymes have optimum operating ranges?
That they work best in the right pH and temperature they were made to work in. Amylase works best in the mouth's pH of about 7, while pepsin works best at a much lower and acidic pH.
In today's experiment what was one method that you used to denature the catalase?
Allow the temperature to go above that catalysts/enzymes operational temperature. e.g. Yeast works at about 37 oC, however, it denatures above 45 oC.
Enzymes are usually inactivated at what temperature?
The optimal range for the enzymatic activity goes from 25oC to 32oC.
How does NaCl affect the rate at which amylase hydrolyse starch?
It speeds up the reaction so amylase works faster.
