Do you expect that optimal PH for pepsin would be the same as that for rennin?
The optimal pH for pepsin and rennin is about the same, 2.0 and 3.4 respectively. Pepsin is slightly more acidic.
Why is pepsin stable at a low pH?
Pepsin is a an acidic proteolytic enzyme activated from its precursor pepsinogen. Pepsin exhibits optimal activit at pH 1.5 to 2. It is highly active and stable at acidic pH and can be inactivated by pH 8.5 -11. Their amino acid composition is the reason for its stability.
What is the pH of Pepsin in NaOH?
it depends on the concentration of NaOH, pepsin, buffer used, ... that cannot be answered in that way...
Why does protein digestion require the presence of both pepsin and HCl?
Protein digestion requires the presence of both pepsin and HCl because pepsin needs an acidic environment to be able to "work" or do its job. Pepsin needs an environment with a pH around 2, which is roughly the pH of HCl. Therefore, HCl aids pepsin in protien digestions by creating an optimal environment for pepsin to work and digest proteins.
Why does pepsin not function well at a pH of 7?
Enzimes are sensitive to pH and function best across a narrow range of pH.
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
What is the pH for pepsin?
Pepsin is a type of protease that works mainly in the stomach. As a result, its optimum pH is around 2. The high acidity is provided by the hydrochloric acid in the stomach.
During digestion the pH in the stomach is 2 What does this indicate about the optimum pH of pepsin?
Pepsin is therefore acidic since the pH in the stomach is 2
Is the optimal pH of trypsin acidic or basic?
The optimum PH of pepsin ranges between 1.0 and 4.0. Pepsin exhibits about 90 percent of the maximum activity and about 35% of the maximum activity.
Do you expect that optimal PH for pepsin would be the same as that for rennin?
The optimal pH for pepsin and rennin is about the same, 2.0 and 3.4 respectively. Pepsin is slightly more acidic.
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 effect the pH have on protein digestion with pepsin?
It is most effective at around pH 2, and becomes inactive over 5.
Why is pepsin stable at a low pH?
Pepsin is a an acidic proteolytic enzyme activated from its precursor pepsinogen. Pepsin exhibits optimal activit at pH 1.5 to 2. It is highly active and stable at acidic pH and can be inactivated by pH 8.5 -11. Their amino acid composition is the reason for its stability.
What enzyme functions at the lowest pH?
pepsin
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,
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
Which enzyme functions best in a pH environment most similar to that of human stomach enzyme?
Pepsin. It is located in the stomach. Pepsin helps with the breakdown of food and is a protein. A pH 2 is optimal for the human enzyme pepsin. If the pH level exceeds 7, pepsin becomes denatured or lose its structure; above pH 5,, it will increase function.
