Respiración Celular En presencia de oxígeno, la etapa siguiente a la glucólisis es la respiración celular que cumple dos etapas: ciclo de Krebs y transporte de electrones terminal. En las células eucarióticas (con núcleo) estas reacciones tienen lugar en las mitocondrias . Allí el ácido pirúvico se oxida a dióxido de carbono y agua, completándose de esa manera la degradación de la glucosa. El 95 % del ATP generado por las células heterotróficas (que no producen fotosíntesis ) se produce en las mitocondrias. El ácido pirúvico, antes de ingresar al ciclo de Krebs, se oxida. Los átomos de carbono del grupo carboxilo (COOH) se eliminan como dióxido de carbono (CO )y queda un grupo acetilo (CH CO) de dos carbonos. Cada compuesto acetilo es aceptado momentáneamente por un compuesto llamado coenzima A forma al acetil coenzima A (acetil Co A) que es el eslabón entre la glucólisis y el cíclo de Krebs. Ciclo de Krebs Es una sucesión de reacciones químicas que ocurren dentro de la célula, mediante las cuales se realiza la descomposición final de las moléculas de glucosa (acetil Co A) y en las que se producen dióxido de carbono, agua y energía. este proceso, que se lleva a cabo por la acción de siete enzimas, es conocido también por ciclo de los ácidos tricarboxílicos. El ciclo de Krebs ocurre en todos los animales, plantas superiores y en la mayoría de las bacterias. En los organismos que tienen células eucariotas (con núcleo), el ciclo tiene lugar dentro de la mitocondria, estructura que se compara a menudo con la central de producción de energía de la célula. El descubrimiento del ciclo es obra de sir Hans Adolf Krebs, un bioquímico británico que presentó este importante avance científico en 1937.

Oh, my God, what are you doing today? You have the dead body of a young woman today. What happened to her? Please tell me." "Just a minute doc. You said that a local doctor has already certified that the cause of death was heart disease. Then what more do you expect to find?" "Tarun, the relatives of Kabuli have already lodged a complaint with the police that she has been done to death by Radhey. Kabuli had got married only a year back. Under the Indian law, any death of a married female occurring within 7 years of marriage is termed as dowry death and is taken seriously. Had there been no complaint from Kabuli's relatives side, then everything would have been fine. But since a complaint has already been lodged, the police naturally want to be doubly sure that Kabuli really died of heart disease or not." "You mean that the local doctor gave a wrong cause of death? Do you?"

De citroenzuurcyclus Kreb's cycle / TriCarboxylic Acid Cycle / TCA Cycle Inleiding: De citroenzuurcyclus bestaat uit een serie chemische reacties die essentieel zijn voor de oxidatieve stofwisseling van glucose en andere eenvoudige suikers. Het doel van de citroenzuurcyclus is de vorming van NADH en FADH voor de ademhalingsketen. De afbraak van glucose tot kooldioxide en water wordt koolhydraat katabolisme genoemd en de citroenzuurcyclus is de derde stap in een proces dat uit vier stappen bestaat. De eerste stap is de glycolyse ; de tweede stap is de oxidatieve decarboxylering ( Het Pyruvate Dehydrogenase Complex zet pyrodruivenzuur om in acetyl co nzym A ) de derde stap is de citroenzuurcyclus en de vierde stap is de oxidatieve fosforylering. De enzymen van de citroenzuurcyclus zijn gelokaliseerd in het mitochondrion evenals de enzymen van het pyruvaat dehydrogenase complex en de enzymen die de bèta oxidatie van de vetzuren uitvoeren. De citroenzuurcyclus vindt plaats in het vloeibaar gedeelte van het mitochondrion ( Matrix). In de glycolyse wordt glucose omgezet in pyrodruivenzuur ( pyruvic acid ). In de eerste stap van de citroenzuurcyclus wordt het acetyl gedeelte ( CH

Citric acid The most versatile and widely used organic acid in foodstuffs, citric acid is a colourless, crystalline organic compound, belonging to the family of carboxylic acids. It is present in practically all plants, and in many animal tissues and fluids, but it is in particularly high concentrations in lemons and other citrus juices and many ripe fruits. First isolated in 1784 from lemon juice, by the Swedish chemist Carl Wilhelm Scheele, citric acid has been used as a food additive for over 100 years. It is normally manufactured by fermentation of cane sugar or molasses in the presence of the fungus Aspergillus niger , but it can also be obtained from pineapple by-products and low-grade lemons. Its use as a food additive is wide and varied - as a synergist to enhance the effectiveness of other antioxidants; as a sharp-tasting flavouring; as a sequestrant in foods it combines with the naturally occurring trace metals to prevent discolouration and in wine production it combines with free iron to prevent the formation of iron-tannin complexes which cause cloudiness; in brewing to reduce excess losses of sugars from the germinated barley; to create an acidic environment to discourage the growth of certain bacteria, yeasts and moulds and in cheese making it produces a faster and more consistent method of producing the necessary acidic environment for the enzyme activity than the traditional souring by lactic acid ( ) caused by bacteria.

Sammy Radstone looks into a few Down's syndrome: John Langdon Haydon Down (1828-96) John Down was born in Cornwall to an Irish-Cornish family in 1828. His scientific interest began as a child and progressed when he left school at the age of 13 to help his father in the pharmacy business. He moved to London at 18 to work as surgeon's assistant in Whitechapel. Down remained there for only a few months because he found work at the laboratories of the Pharmaceutical Society in Bloomsbury Square, London. Down entered London Hospital Medical School at the age of 25. He excelled as a student and was predicted a brilliant career as a hospital doctor by his teachers. However, he surprised everyone by taking a post at the Earlswood Asylum for Idiots in Surrey in 1858. The next year Down was elected as an assistant doctor to the London Hospital and spent the next decade sharing his time between the two institutions.

Citric acid cycle The citric acid cycle (also known as the tricarboxylic acid cycle , the TCA cycle, or the Krebs' cycle ) is a series of chemical reactions of central importance in all aerobic cells. It is a series of chemical reactions of central importance in all living cells that utilize oxygen as part of cellular respiration . In these aerobic organisms , the citric acid cycle is a metabolic pathway that forms part of the break down of carbohydrates fats and proteins into carbon dioxide and water in order to generate energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production. The citric acid cycle also provides precursors for many compounds such as certain amino acids , and some of its reactions are therefore important even in cells performing fermentation The citric acid cycle is also known as the Krebs' cycle after Sir Hans Adolf Krebs (1900-1981), who proposed the key elements of this pathway in 1937 and was awarded the Nobel Prize in Medicine for its discovery in The citric acid cycle takes place within the mitochondria in eukaryotes , and within the cytoplasm in prokaryotes Fuel molecule catabolism (including glycolysis ) produces acetyl-CoA , a two- carbon acetyl group bound to coenzyme A . Acetyl-CoA is the main input to the citric acid cycle. Citrate is both the first and the last product of the cycle (Fig. 1), and is regenerated by the condensation of
