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
Is a lake with a low pH acidic or basic?
acidic below 7 is acidic, above 7 is a base, and 7 is neutral.
PH range of pepsin?
pepsin is activated from pepsinogen in stomach. the pH range for its optimal ativity is at acidic pH between 1.5 to 2. It is also stable upto pH8 and can be inactivated at basic pH from 8.5,
Is pH 9 more acidic than pH 4?
No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.
What is the neutral PH?
A Ph of 7 is neutral, anything more is acidic, anything less is basic.
Is the optimal pH of tryspin acidic or basic?
Basic. Trypsins have an optimal operating pH of about 8(and optimal operating temperature of about 37°C)
What pH do neither trypsin or pepsi work in?
Both trypsin and pepsin have optimal activity at specific pH levels, with trypsin functioning best around pH 7.5-8.5 and pepsin operating effectively at a much lower pH of around 1.5-2.5. Neither enzyme works effectively in a neutral pH of 7, where trypsin is too inactive, and pepsin is too far from its optimal acidic environment. Therefore, a neutral pH of 7 is unsuitable for the activity of either enzyme.
Compare the optimum pH levels for trypsin and pepsin. how is the optimal pH level of pepsin relevant to it's particular location in the body?
pepsin is found in the stomach and the pH there is 2 while trypsin is found in the small intestine (duodenum and jejunum) and the pH there is 8-9. Thus, the optimum pH levels for pepsin and trypsin are 2 and 8-9 respectively.
What pH does trypsin work at the best?
The optimal pH for trypsin is 8. It is found in the small intestine and digests proteins and polypeptides there.
Can enzymes function at any pH?
No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.
What does acidic basic mean?
Substances are described as 'Acidic' if their pH < 7 Substances are described as 'Basic' if their pH > 7 Substances with a pH = 7 are described as neutral(a chemical salt). There is no such descriprtion as 'Acidic Basic'. They are contradictory!!!!

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.
Which ranges on the pH scale are acidic basic and neutral?
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
Is the pH value of 1.2 as acidic or basic?
A pH value of 1.2 is acidic. pH values below 7 are considered acidic, while pH values above 7 are basic.
What is acidic and alkaline in pH?
pH<7 -----> Acidic pH=7------> Neutral pH>7------>Basic or Alkaline
Is a soltion with a pH of 2 acidic or basic?
it will be acidic
