Kreb's cycle is also known as TCA cycle. this step occurs after glycolysis. the tca accounts for abt two-thirds of the total oxidation of carbon compounds in most cells, and its malor end pdts are carbon dioxide and high energy electrons in the form of NADH . The carbon dioxide released is a waste pdt while the NADH are passed to a membran - bound electron transport chain. ,eventually combining with oxygen to produce water. this takes place in the mitochondria.\nthe first step is-\nthe citric acid cycle , results in complete oxidation of the carbon atoms of the acetyl groups in acetyl-CoA,converting them into carbon dioxide.But the acetyl group is not oxidized  directly . Instead,this group is transferred from acetyl- CoA  to a larger, four carbon molecule , oxaloacetate, to form the six carbon CITRIC acid. ENZYME involved is-citrate synthetase.\n\nstep two-\nCitrate is converted to isocitrate with the removal of water from citrate ... enzyme involved is ACONITASE...\n\nSTEP three-\nIsocitrate is  converted alpha- ketoglutarate....here NAD+ is NADH... enzyme involved is isocitrate dehydrogenase.\n\nSTEP four-\nalpha- ketoglutarate is converted to succinyl-CoA. here NAD+ is NADH... enzyme involved is alpha-Ketoglutarate dehydrogenase complex.\n\nSTEP five-\nSuccinyl Co-A is converted to succinate .here GTP is converted GDP. enzyme involved is succinyl -CoA synthetase.\n\nSTEP six-\nsuccinate is converted to fumarate. here FADH2 is converted to FAD . enzyme involved is succinate dehydrogenase..\n\nSTEP seven-\nfumarate is converted to malate... enzyme involved is fumerase..\n\nSTEP eight-\nmalate is converted to oxaloacetate..here NAD+ is converted NADH... enzyme involved is malate dehydrogenase... \n\nagain this oxaloacetate combines acteylCoA to form citric acid.. again ...and the cycle continues...

The step from pyruvate (CH3COO-) to Acetalaldehyde (CH2CHO) and CO2 is done by the enzyme pyruvate decarboxylase.  The step from Acetalaldehyde to ethanol (CH3CH2OH) is Alcohol dehydrogenase.  I do not have the chemical structures for the enzymes, because they would be way complicated, but I think what you are looking for is.\n\nC6H12O6 + 2ADP + 2 Pi = 2 CH3CH2OH + 2 CO2 + 2ATP + 2H20

The enzyme catalase is a protein molecule. Its shape, particularly the shape of the active site, is changed by variation of pH from pH7.\nGreater the change away from about pH7, greater the alteration of shape.\nAs the shape of the active site changes the enzyme is less and less effective.\nIncreases or decreases in pH will reach the point where the enzyme's shape is permanently changed - the enzyme is denatured.

Glycolysis -- Cytoplasm\nKrebs Cycle(TCA) -- Matrix\nETS -- INNER membrane \nThe Krebs cycle, also called the citric acid cycle, is a fundamental metabolic pathway involving eight enzymes essential for energy production through aerobic respiration, and, like glycolysis, arose early in evolution. This pathway is also an important source of biosynthetic building blocks used in gluconeogenesis, amino acid biosynthesis, and fatty acid biosynthesis. The Krebs cycle takes place in mitochondria where it oxidizes acetyl-CoA, releasing carbon dioxide and extracting energy primarily as the reduced high-energy electron carriers NADH and FADH2. NADH and FADH2 transfer chemical energy from metabolic intermediates to the electron transport chain to create a different form of energy, a gradient of protons across the inner mitochondrial membrane. The energy of the proton gradient in turn drives synthesis of the high-energy phosphate bonds in ATP, the common energy currency of the cell used to drive a huge variety of reactions and processes. An acetyl-CoA molecule (2 carbons) enters the cycle when citrate synthase condenses it with oxaloacetate (4 carbons) to create citrate (6 carbons). One source of the acetyl-CoA that enters the Krebs cycle is the conversion of pyruvate from glycolysis to acetyl-CoA by pyruvate dehydrogenase. Acetyl-CoA is a key metabolic junction, derived not only from glycolysis but also from the oxidation of fatty acids.

Nucleoside Deoxyribosyltransferase is an enzyme that catalyses the cleavage reaction of purines and pyrimidines.  Basically, the idea is that the hydrogen bonds that hold the two strands together will break spontaneously as the result of a really slow reaction.  NDRT speeds that reaction up a lot (cause that's what catalysts do) so the strands separate.  If you're looking for more detailed explaination than that, you can try to make sense of the article listed below.

FATTY ACIDS\n\n\nCarboxylic acids occur in many molecular forms. At first It must be recalled that if the majority of the fatty acids found in lipids are monocarboxylic acids, some of them are dicarboxylic and constitute important metabolic or oxidation products of the previous ones. \n   \nSeveral hundreds of forms have been identified but the number occurring frequently in the common lipids is much fewer (from 10 in plants to about 20 in animal tissues). Several fatty acids, free or esterified (methyl butyrate, ethyl octanoate, dodecanoic acid...), belong to aroma compounds which are found in environmental or food systems (see the website: Flavornet). Fatty acid methyl and ethyl esters are known to be present in the plasma of patient with liver dysfunction following ethanol ingestion (Aleryani SL et al., Clin Chim Acta 2005, 359, 141).\n\n\nFatty acid classification\n\n\nTriglycerides from various vegetable oils give through transesterification a mix of fatty acid esters which is now used increasingly as a substitute of diesel fuel and is named Biodiesel.\n\nThe world production of fatty acids from the hydrolysis of natural fats and oils totaled about 4 million metric tons per year. Fatty acids are ultimately consumed in a wide variety of end-use industries (rubber, plastics, detergents...). As it is a good indication of the overall economic performance of a region, the consumption of fatty acids has tended to approximate the growth in the GNP of the region of their consumption.\n\n\n\n\n\nTo describe precisely the structure of a fatty acid molecule, one must give the length of the carbon chain (number of carbon), the number of double bonds and also the exact position of these double bonds, this will define the biological reactivity of the fatty acid molecule and even of the lipid containing the fatty acids studied.\n\nMost fatty acids are straight-chain compounds with the most frequently an even number of carbon atoms. Chain-lengths range is from 2 to 80 but commonly from 12 up to 24. With a chain length from 2 to 6 (or 4) they are called short-chain, from 8 (or 6) to 10 they are called medium-chain and 12 up to 24 they are called long-chain fatty acids. Their physical and biological properties are related to this partition in 3 classes.\nAn extensive review on the biochemical mechanisms of fatty acid elongation may be consulted for further information (Leonard AE et al., Prog Lipid Res 2004, 43, 36).  \n\nFatty acids are simple in structure and even with their derivatives can be subdivided into well-defined families:\n\nAmong straight-chain fatty acids, the simplest are referred to as saturated fatty acids. They have no unsaturated linkages and cannot be altered by hydrogenation or halogenation. When double bonds are present, fatty acids are said unsaturated, monounsaturated (MUFA) if only one double bond is present and polyenoic (or polyunsaturated fatty acids =  PUFA) if they have two or more double bonds generally separated by a single methylene group (methylene-interrupted unsaturation). In recent physiological works, the last class is used only for fatty acids with three up to six double bonds as those found in fish oil or in brain tissue. Some uncommon polyunsaturated fatty acids have two adjacent double bonds separated by more than one methylene group, they are named polymethylene-interrupted fatty acids.\n\nIn some animals, but mainly in plants and bacteria, fatty acids may be more complex since they can have an odd number of carbon atoms, branched chains or contain a variety of other functional groups, including acetylenic bonds, epoxy-, hydroxy- or keto groups and even ring structures (cyclopropane, cyclopropene, cyclopentene, furan, and cyclohexyl) or a coenzyme A moiety (acyl CoA).\n\nExcept fatty acyl-CoA, we have based our classification of fatty acids first on the type of carbon chain : either straight (or normal), or branched, or containing a carbon ring. In each category, subdivisions are created according

You were close by looking at wikipedia. The image is a ball and stick but you could figure it out. The description says it is just fatty acids (usually alkyl C16-C18) chains attached by an ester bond to the hydroxyls of a sucrose molecule (8 fatty acids).
