Answer:
Liver.
Explanation:
The liver is a dark reddish organ that is situated in the right hypochondriac or upper right hand region of the abdomen, just below the diaphragm and anterior to the stomach in the epigastric region, the right kidney and the small intestines.
It is the second largest organ of the body, second only to the skin. The liver is divided into four lobes which include;
1) The right lobe
2) The left lobe
3) The quadrate lobe and
4) The caudate lobe
The blood supply to the liver include;
1) The hepatic artery
2) The hepatic portal vein which supplies the liver with nutrients-filled blood from the small intestine. It is the main blood supply to the liver.
The venous drainage is through the hepatic veins.
The nerve supply is through the hepatic plexus made up of sympathetic and parasympathetic nerves.
The liver plays a major role in the processing and metabolism of food and ingested substances and also detoxification.
Polyurethanase is an enzyme emitted by the microorganism so as to break polyurethane. Since the polymer is a significant wellspring of energy for the life form, it should be separated all together for etpum"s development.
Further details
Polyurethane
It is a polymer made out of organic units and carbamate links join them. While most polyurethanes are thermosetting polymers that don't liquefy when warmed, thermoplastic polyurethanes are likewise accessible. Polyurethanes are available in numerous parts of present-day life. They present a class of polymers that have discovered a far-reaching use in the medical and mechanical fields. Polyurethanes can be found in items such as furniture, coatings, cement, constructional materials, paints, elastomers, filaments and paddings. Polyurethane ought to be curtailed to PUR in consistence with authority German and International benchmarks.
Polyurethanase
It can be defined as such an enzyme which is secreted by microbes and used for the breakdown of polyurethane. In this breakdown process energy is released that is utilized by microorganisms.
Bio-degradation of Polyurethane
In spite of their microbial obstruction, polyurethane is attacked by microscopic organisms however the component to explain its bio-degradation is unknown. There are reports from microscopic organisms and parasites that are equipped for the breakdown of polyurethane yet the examinations about the proteins that assault the plastic are centered around bacterial compounds as it were. The enzyme is of sort esterase and protease for the most part since these chemicals are unspecific and can perceive a few regions in the polyurethane particle and hydrolyze it.
