Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme with lowest pH optimum is pepsin. Pepsin works in the stomach in an acidic environment and aids in digestion.
Do all enzymes work best at neutral pH?
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
What is needed to digest proteins?
Mainly, the enzyme Protease breaks up proteins into amino-acids. Also, proteins contain nitrogen which the body cannot use. Water is required to remove this nitrogen, bonding with if to form ammonia. This is subsequently secreted in urine.
How does pH affect enzyme activity Use the enzymes pepsin and trypsin as examples?
Enzymes work within a range of pH levels. Pepsin, which is found in the stomach works in an acidic environment, while trypsin functions in a basic surrounding in the intestines. Increasing or decreasing the pH levels can stop the activity of these enzymes.
Would trypsin work well in the stomach?
No. The stomach is highly acidic (~2pH) while trypsin works well in the neutral/basic environment of the small intestine.
Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme with lowest pH optimum is pepsin. Pepsin works in the stomach in an acidic environment and aids in digestion.
What is the enzyme that works in both acidic and basic pH?

What does the enzyme protein digest?
The general term is "proteases" Pepsin cleaves at the "n" terminus produced by the stomach and works in an acidic pH environment. Chymotrypsin and Trypsin are produced by the pancreas which is below the stomach and work in a more basic pH environment.
Do all enzymes work best at neutral pH?
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
What type of enviorment does pepsin work best in?
The optimum pH of pepsin is pH2. Pepsin is found in the stomach and it is protease enzyme that digest protein into smaller molecule. The stomach is suitable place for it because it is acidic , so it's activity increases in the acidic environment.
Enzyme found in gastric juices?
the enzyme found in gastric juice is Pepsinogenand it only works in an acidic environment (hydrochloric acid is in the stomach)then when that enzyme gets mixed with the hydrochloric acid it creates pepsin and pepsin breaks down proteins into amino acid chainsthere are also other enzymes like:HClReninPepsinogenGelatinaseGastric AmylaseGastric Lipase
What is a gastric protease?
It is an enzyme that is produced in the stomach and used to digest proteins to polypeptides. It works best in acidic conditions
Where do digestive enzymes work best in either a neutral basic or acidic environment?
Digestive enzymes work best in a slightly acidic environment rather than a neutral environment. That's the reason why the stomach releases gastric acid.
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.
Pepsin a digestive enzyme found in the stomach works best at a pH near?
Pepsin works best in acidic environments and it's optimal pH (the pH at which it works best) is 2.0
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
Do enzymes in the small intestine need an acidic environment in order to work?
No, the small intestine do not need an acidic environment in order to work. Acid works in stomach to partially digest the food. In the small intestines, fats are digested using bile from the gallbladder which is not acidic.
