Are the digestive enzymes produced by the pancreas produced as inactive precursors or are they activated in the digestive tract by proteolysis?
The digestive enzymes produced by the pancreas are typically produced as inactive precursors (zymogens). These inactive forms are activated in the digestive tract when specific proteases cleave them to their active forms, ensuring they are only active when needed for digestion.
Do uncompetitive inhibitors bind to the active site of enzymes?
No, uncompetitive inhibitors do not bind to the active site of enzymes. They bind to a different site on the enzyme, causing a conformational change that prevents the substrate from binding to the active site.
The enzyme pepsin is produced in the cells of the stomach but not in the cells of the small intestine The small intestine produces a different enzyme trypsin The reason that the stomach what?
The reason the stomach produces pepsin is because pepsin is active in the acidic environment of the stomach, which is needed to break down proteins into peptides. Trypsin, produced in the small intestine, functions in a less acidic environment and helps further break down peptides into smaller molecules for absorption. This specialization allows the different digestive enzymes to work effectively in their respective environments.
Do enzymes in the digestive tract catalyze hydrolysis reactions?
enzymes catayze chemical reaction where Eva the substrate and active site meet wheather that be in you mouth stomach , larger /smaller intesine or lower gut of whitch the biological enzymes are found.
Which organelle produces enzymes?
The organelle that produces enzymes is the endoplasmic reticulum, specifically the rough endoplasmic reticulum. It is studded with ribosomes that synthesize proteins, including enzymes, which are then processed and modified before being released into the cell.

Which digestive enzymes are active at site different from the site where they are produced?
Trypsin, lipase, chymotrypsin, pancreatic amylase, steapsin, elastases, carboxypeptidase, and nucleases. ~answered by FightingLucario
Which digestive enzymes are active at a different site from the site where they are produced?
Trypsin, lipase, chymotrypsin, pancreatic amylase, steapsin, elastases, carboxypeptidase, and nucleases. ~answered by FightingLucario
Why are proteolytic enzymes produced in an inactive form?
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
Which of these digestive enzymes are active under strongly acidic conditions?
We need more information as to which enzymes you are asking about.
Why are many enzymes involved in the digestive system?
There are many different types of enzymes because each type have a differently shaped active site (the place where the reaction takes place) and the reaction can only happen if the active site is the right shape for the food molecule. eg. Protease enzymes break down proteins.
What is the subtrate for enterokinase?
The substrate for enterokinase is trypsinogen, an inactive precursor of the digestive enzyme trypsin. Enterokinase, produced in the intestine, activates trypsinogen by cleaving it to form active trypsin. This activation is crucial for the digestive process, as trypsin further activates other proteolytic enzymes.
Which digestive enzyme are active at a site different from the site where they are produced?
Trypsin, lipase, chymotrypsin, pancreatic amylase, steapsin, elastases, carboxypeptidase, and nucleases. ~answered by FightingLucario

No, uncompetitive inhibitors do not bind to the active site of enzymes. They bind to a different site on the enzyme, causing a conformational change that prevents the substrate from binding to the active site.
The graph illustrates the activity level of three common digestive enzymes across a range of pH values. Which enzyme is likely to be active in the acidic environment of the stomach?
The enzyme likely to be active in the acidic environment of the stomach is pepsin. Pepsin is designed to function optimally at a low pH, typically around 1.5 to 3.5, which corresponds to the acidic conditions found in the stomach. In contrast, other digestive enzymes such as amylase and lipase are more active in neutral to alkaline pH levels.
What causes enzymes to be different from one another?
Enzyme specificity is mainly determined by the unique structure of their active site, which allows them to bind to specific substrates. This specificity arises from the unique sequence and conformation of amino acids that make up the active site, which are dictated by the enzyme's genetic code. Additionally, the 3D shape of enzymes is influenced by their environment, such as temperature and pH, which can affect their function and specificity.
