What was the result of mixing the boiled enzyme with milk?
Once you boil the enzyme, it will be inactivated. Milk will have no effects of the enzyme.
What happens to an enzyme-substrate reaction when the enzyme has been subjected to heat or high-low pH?
When an enzyme is subjected to heat or extreme pH levels, it can denature, losing its specific shape and functionality. This can affect the enzyme's ability to bind to the substrate and catalyze the reaction efficiently. In extreme cases, the enzyme may become permanently inactivated.
What happens to an enzyme when it is destroyed?
When an enzyme is destroyed, its structure is altered by factors such as high temperature or extreme pH, resulting in loss of its catalytic activity. Once destroyed, an enzyme cannot perform its biological function, leading to impaired biochemical reactions in the cell or organism. The destroyed enzyme is typically broken down into its component amino acids by proteolytic enzymes in the body.
What is the gastric enzyme that acts on proteins?
The proteolytic or protein eating enzyme of the stomach is called pepsin. Pepsin is secreted into the stomach as a zymogen (or inactive enzyme precursor) called pepsinogen which is converted into the active enzyme form by the hydrochloric acid and low pH in the gastric juices.
Proteolytic enzyme secreted as proenzyme in GI tract-why?
Proteolytic enzymes are secreted as proenzymes in the gastrointestinal tract to prevent damage to the cells that produce them and to regulate their activity. This ensures that the enzymes only become active when they reach their target site in the intestines, where they can safely break down food proteins into smaller peptides and amino acids for absorption.
What was the result of mixing the boiled enzyme with milk?
Once you boil the enzyme, it will be inactivated. Milk will have no effects of the enzyme.
Which proteolytic enzyme induces lysis of fibrin during fibrinolysis?
Plasmin is the proteolytic enzyme that induces the lysis of fibrin during fibrinolysis. Plasmin breaks down fibrin into soluble fragments, which helps dissolve blood clots.
What is least likely to be a mechanism for enzyme regulation?
Change in enzyme concentration through gene expression.
Location and function of pepsin?
pepsin is a proteolytic enzyme present in the gastric glands.it hydrolyses proteins into peptones.
Does proteolytic enzymes cause denature of proteins?
Yes, proteolytic enzymes break down proteins by cleaving peptide bonds. This process may result in protein denaturation, especially if the enzyme cleaves at specific sites that disrupt the protein's structure and function.
What is the enzyme that inactivates cAMP?
cAMP is inactivated by the enzyme phosphodiesterase (PDE), which breaks down cAMP into its inactive form, AMP. This process regulates the signaling pathway controlled by cAMP in cells.
What happens to an enzyme-substrate reaction when the enzyme has been subjected to heat or high-low pH?
When an enzyme is subjected to heat or extreme pH levels, it can denature, losing its specific shape and functionality. This can affect the enzyme's ability to bind to the substrate and catalyze the reaction efficiently. In extreme cases, the enzyme may become permanently inactivated.
What is phosphatase test in milk?
The phosphatase test in milk measures the amount of phosphatase enzyme in the milk. The phosphatase enzyme should be inactivated by pasteurisation. If the phosphatase test is not negative, there is a problem with pasteurisation or recontamination with unpasteurised milk.
What does inactivate mean?
Enzyme inactivation refers to a certain period when the enzyme is unable to catalyse a particular reaction. For example some enzymes are inactivated at extreme temperatures of cold or heat. At this particular time the enzyme does not perform its function of catalysis but after favourable conditions return the enzyme wil resume its catalylitic function.
Which antigen is being destroyed by proteolytic enzyme treatment of red cells?
Proteolytic enzyme treatment of red cells destroys A and B antigens, which are present on the surface of red blood cells. This process is often used to convert group AB red cells into group O red cells for safe transfusion to patients with severe blood type mismatches.

Why amylase is inactivated in the mouth by very hot drinks?
Amylase is an enzyme responsible for breaking down starches into simpler sugars. However, amylase is sensitive to temperature and can be denatured or inactivated at high temperatures. When very hot drinks are consumed, the high temperature can denature the amylase enzyme in the mouth, rendering it ineffective in breaking down starches. This can impact the digestion process and reduce the efficiency of starch breakdown in the mouth.
