What is the enzyme in the liver and enzyme activity?
Liver contains a specific enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the products of oxygen gas (O2) and liquid water (H2O). The purpose of this lab is to determine if changes in temperature will have an effect on the activity of an enzyme.
What is the enzyme in the liver lab?
Liver and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide, which is a harmful by-product of the process of cellular respiration if it builds up in concentration in the cells.
How do enzymes work in the liver?
Liver enzymes are proteins that speed up chemical reactions in your body. These chemical reactions include producing bile and substances that help your blood clot, breaking down food and toxins, and fighting infection. Common liver enzymes include: Alkaline phosphatase (ALP).
Why does the liver activate enzymes?
Often these reactions require “help” to happen at a faster speed, and this can be supplied by enzymes—tiny types of proteins. The liver uses specialized enzymes to help it break down toxic substances and make them safer for the body to process.
What is the most important liver enzyme?
Like ALT, AST is normally present in blood at low levels. An increase in AST levels may indicate liver damage, disease or muscle damage. Alkaline phosphatase (ALP). ALP is an enzyme found in the liver and bone and is important for breaking down proteins.
What foods elevate liver enzymes?
Lemons, limes and grapefruits are all natural sources of vitamin C and contain many potent antioxidants. Like garlic, citrus fruits have the ability to boost the production of liver detoxification enzymes.
What are the enzymes produced by the liver?
When the liver is damaged, overworked or diseased, its walls become perforated. As a result of this, enzymes escape the liver and enter the bloodstream. The most common enzymes produced by the liver are: Aspartate aminotransferase (AST) and alanine transaminase enzymes (ALT).
What are the names of the liver enzymes?
Liver enzymes are found in normal plasma and serum and can be divided into different groups. Aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT). Together these enzymes are known as transaminases. Alkaline phosphatase (AP) and gammaglutamyl transferase ( GGT ) are known as cholestatic liver enzymes.
What are the reasons for elevated liver enzymes?
Most common causes for elevation of liver enzymes are alcohol abuse, medications such as pain relievers, medications for seizures, antibiotics, and medications to lower cholesterol levels, antidepressant drugs, niacin , and cardiovascular drugs. An overweight or fatty liver may also cause liver enzymes to be elevated.
