The stomach is usually a highly acidic environment due to gastric acid production and secretion which produces a luminal pH range usually between 1 and 4 depending on food intake and other factors. Such an environment is able to break down large molecules (such as from food) to smaller ones so that they can eventually be absorbed from the small intestine. The stomach can produce and secrete about 2 to 3 litres of gastric acid per day

At what pH would the enzyme be most effective?
It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.
At what pH is the rate of enzyme activity the highest?
Pepsin secreted in the stomach, works at highly acidic pH and the pH could be as low as 2. The optimal pH for pepsin is thus near about 2. This pH is maintained by HCl secreted by the gastric glands in the stomach.
What is the optimum pH for stomach protease?
Pepsin is an enzyme that catalyzes the breakdown of proteins int peptides. Its optimum pH range is between 1 to 4.
What are the optimum temperature and the optimum pH of an enzyme?
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
Can pepsin and trypsin function in the same environment-?
no they can not because they at completely different pH levels.
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's optimum pH?
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
Why does stomach acid have to have a very low pH level and how that level affects digestion?
The cells of the stomach make an pro-enzyme called pepsinogeen. When pepsinogeen is secreted in the acidic (pH 2-3) environment of the stomach it transforms into pepsine, an enzyme wich breaks down proteins. If pepsine was made directly in the cells, it would destroy the cell before it would secreted in the stomach.
Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells?
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
Does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach?
The optimum pH for tryspin is about 8.0, which is the pH of the intestine, whereas the pH of gastric juice is 1.5-2.0, which is highly acidic.
