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 enzymes perform major proteolytic activities in the digestive tract?
The major proteolytic enzymes in the digestive tract are pepsin, trypsin, chymotrypsin, and elastase. Pepsin is mainly found in the stomach, while trypsin, chymotrypsin, and elastase are produced in the pancreas and released into the small intestine to further break down proteins into smaller peptides and amino acids for absorption.
Which enzyme breaks down protein?
Pepsin is the enzyme that breaks proteins into peptides.
Which two enzymes would be active in the stomach?
The small intestine receives the secretion of two glands : liver and pancreas. liver secretes bile and pancreas secrete pancreatic juice which contain pancreatic amylase and trypsin and lipase.
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.
Are pepsin and trypsin classified as sugars?
pepsin and trypsin are classified as proteins
What are the similarities of pepsin and trypsin?
Pepsin and trypsin both are protein digesting enzymes.
Pepsin and trypsin are classified as what?
They are classified as proteins
What does Pepsin and Trypsin acid in?
poopy stain
Can pepsin and trypsin function in the same environment-?
no they can not because they at completely different pH levels.

Which of the enzyme-substrate pairings is incorrect Nuclease-DNA Trypsin-protein Pepsin-carbohydrate Amylase-starch or Lipase-fat?
Trypsin-carbohydrates
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.
What enzymes perform major proteolytic activities in the digestive tract?
The major proteolytic enzymes in the digestive tract are pepsin, trypsin, chymotrypsin, and elastase. Pepsin is mainly found in the stomach, while trypsin, chymotrypsin, and elastase are produced in the pancreas and released into the small intestine to further break down proteins into smaller peptides and amino acids for absorption.
What might the graph of a pepsin and tryspin indicate about the relative acidity of the stomach of the small intestine?
The graph of pepsin and trypsin activity would likely show that pepsin is more active in acidic conditions, typical of the stomach, while trypsin exhibits optimal activity in a more neutral to slightly alkaline environment, characteristic of the small intestine. This difference indicates that the stomach's acidity facilitates protein digestion by pepsin, whereas trypsin operates effectively when the pH rises after chyme enters the small intestine. Consequently, the graph would highlight the contrasting pH preferences of these digestive enzymes and their respective roles in the digestive process.
Why is Pepsin replaced by Trypsin in the small intestine?
Unlike pepsin, trypsin is secreted by the pancreas into the small intestine, explains Dr. Gary Thibodeau in his book "Anatomy and Physiology." It also breaks the bonds between amino acids, but it focuses on different amino acid bonds. Specifically, trypsin breaks the bonds that follow the amino acids lysine and arginine. Since different proteolytic enzymes can break different bonds, many enzymes have to work together to break a protein down completely.
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.
