Write a short note on reaction catalyzed by lactate dehydrogenase

State True or False Q. This movement is called wobble and allows a single tRNA to recognize more than one codon.

3 Steps of Glycolysis:

The result of the wobbling is that there need to be 61 codons coding for amino acids. The examples of traditional and nontraditional base pairing are required to be given between the codon and the anticodon.

Some of them are direct reacting and some are procarcinogens and are converted to ultimate carcinogens in the body. Mechanism of chemical carcinogenesis- the chemicals can be- Direct reacting-which can interact directly with the target molecule. Procarcinogens- are not chemically reactive.

In the body after metabolism they are converted to ultimate carcinogens which are highly reactive. This process of conversion is called metabolic activation. The enzyme systems involved in metabolic activation are cytochrome P species present in the endoplasmic reticulum of cells. Hence chemical carcinogens are mutagens.

C Nucleotide Excision repair- The exposure of a cell to ultraviolet light can result in the covalent joining of two adjacent pyrimidines Usually Thymines producing a dimer. These thymine dimers prevent the DNA polymerase to further replicate the DNA strand beyond the site of dimer formation. The dimers are excised in prokaryotes by Nucleotide excision repair.

The similar mechanisms operate in human beings. Excision of damaged DNA-Next an excision endonuclease recognizes the incision made by the endonuclease.

The stretch of the DNA containing the dimer is removed and the gap is filled by using the sister strand as a template by DNA polymerase. The nick is sealed by DNA ligase.

Xeroderma pigmentosum-The pyrimidine dimers can be formed in the skin cells of humans exposed to UV light. The most common form of the disease is caused by the absence of the UV specific endonuclease.

This may be due to metabolic products of carbohydrates such as oxaloacetate, pyruvate and alpha keto glutarate which provide the carbon skeleton for the formation of non essential amino acids through transamination.

Carbohydrates reduce the requirement of the amino acids for gluconeogenesis. Both carbohydrates and fats are oxidized to produce energy and thus spare the proteins to be used for this purpose.

Lactate Lactate dehydrogenase (a; 10 pts) Why do these fermentative processes occur (same reason for both)? How does short supply (the empty stomach), speculate on the physiological consequences. [Note: the Assume that catalysis is simply a phosphoryl transfer catalyzed by proximity and orientation, followed by a spontaneous. Glucosephosphate dehydrogenase (G6PD or G6PDH) (EC ) that does not seem to participate directly in the reaction catalyzed by G6PD. The evolutionary purpose of the NADP + structural site is unknown.

It is the short term supply of ATP in muscle that has an even more powerful delta G naught prime than ATP- kJ/mol. • Write a balanced equation to describe the reaction catalyzed by pyruvate dehydrogenase.

Normal ratio in blood — NaHCO3:Pyruvate - Lactate Which one ends Glycolysis? Glycolysis ends with the synthesis of pyruvate.

What is Glycolysis?

Note that in animals and plants the electrons in NADH are transferred to pyruvate which reduces the carbonyl carbon in the The reaction catalyzed by lactate dehydrogenase is reversible. This allows a cell to synthesize glucose from lactate. consumed during the reaction they catalyze.

[Note: Some types of RNA can act like enzymes, usually catalyzing the cleavage and synthesis of phosphodiester bonds; RNAs Most enzyme-catalyzed reactions are highly efficient, lactate dehydrogenase and adenylate cyclase. [Note: Some enzymes retain their original trivial names, which give .
