Describe the process of urea formation |
| Answer» ience MENUExplain the formation of urea in the body. Describe the path taken by urea from the organ till it leaves the bodyprint Print document PDF list CiteExpert Answers infoTROPHYHUNTER1 eNotes educator | CERTIFIED EDUCATOR Whenever one consumes proteins, after using the amino acids in the body for protein synthesis, the waste product that is produced is urea. Urea is soluble in water. It is how nitrogen is excreted by the body. The body is unable to store excess protein. Therefore, after digestion by the stomach and small intestine, the amino acids which are protein\'s endproducts enter the bloodstream. Excess amino acids are converted in the liver to other products by the process of deamination. The nitrogen in the amino acid becomes converted to ammonia, and this is further converted by the liver into urea, which is less toxic than ammonia to the body. The kidneys will then filter out the urea from the circulation, send it to the bladder along with water and excrete it in the form of urine. | |

|
Answer» \tOligosachharides contain 2 to 9 monosaccharides.\tOligosaccharides are basically classsified as disaccharides, trisaccharides, tetrasaccharides, pentasachharides and so on depending upon the number of monosaccharides present in the sugar.\tFructo-oligosaccharides and inulin oligosaccharides consist of short chains of fructose molecules, while galacto-oligosaccharides consist of short chains of galactose molecules. All three types of oligosaccharides occur naturally. An oligosaccharides is a saccharide polymer containing small number of monosaccharides. |

what is rubisco |
| Answer» Rubisco stands for\xa0Ribulose bisphosphate carboxylase.\xa0Rubisco is a carboxylase/oxygenase enzyme which plays a dual role in Calvin cycle. This is because the active site of enzyme is same for both carboxylation and oxygenation reactions.*Ribulose bisphosphate carboxylase is an enzyme which catalyses the combination of RuBP with carbo dioxide to give rise to two molecules of phosphoglyceric acid (PGA) during Calvin cycle.*When there is less concentration of Carbon dioxide and high Oxygen concentration, RuBP is oxidised to one molecule of phosphoglycolate and one molecule of PGA during Calvin cycle. | |

Give the examples of Acidic, basic and neutral amino acids respectively. |
| Answer» There are three\xa0amino acids\xa0that have\xa0basic\xa0side chains at\xa0neutral pH. ... For these\xa0amino acids, the protonated forms predominate at physiological\xa0pH\xa0(about 7). Two\xa0amino acids\xa0have\xa0acidic\xa0side chains at\xa0neutral pH. These are aspartic\xa0acid\xa0or aspartate (Asp) and glutamic\xa0acid\xa0or glutamate (Glu).\xa0Histidine is the\xa0most basic amino acid\xa0in the given compound. This can be attributed to the fact that the histidine contains the\xa0most\xa0number of a\xa0basic\xa0nitrogen atom.\xa0Normally, an\xa0amino acid\xa0produces a nearly\xa0neutral\xa0solution since the\xa0acid\xa0group and the basic amine group on the root\xa0amino acid\xa0neutralize each other in the zwitterion. If the\xa0amino acid\xa0structure contains two\xa0acid\xa0groups and one amine group, there is a net\xa0acid\xa0producing effect. | |

Explain electron transport system in brief |
|
Answer» Ncert padho sab diya hua h \tThe metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system (ETS).\tElectron transport system takes place in inner mitochondrial membrane.\tElectron transport chain comprises of the following:\tComplex I: NADH dehydrogenase\tComplex II: succinate dehydrogenase\tComplex III: cytochromes bc1\tComplex IV: cytochromes a-a3\tComplex V: ATP synthase\tNADH2 is oxidized by NADH dehydrogenase and electrons are then transferred to ubiquinone located in the inner mitochondrial membrane.\tFADH2 is oxidized by succinate dehydrogenase and transferred electrons to ubiquinone.\tThe reduced ubiquinone is then oxidized with transfer of electrons via cytochromes bc1 complex to cytochrome c.\tCytochrome c is a small protein attached to the outer surface of the inner membrane and transfer electrons from complex III to complex IV.\tWhen electrons transferred from one carrier to another via complex I to complex IV, they are coupled to ATP synthesis of ATP from ADP and Pi.\tOxygen plays a vital role in removing electrons and hydrogen ion and finally helps in the production of H2 |

What is GFR |
| Answer» Glomerular Filtration Rate (GFR): The amount of the filtrate formed by the kidneys per minute is called glomerular filtration rate (GFR).
