Explain the role of Acetyl Co-A formation from glucose catabolism.?
104634
Acetyl-CoA is generated in the mitochondria primarily from two sources, the pyruvate dehydrogenase (PDH) reaction and fatty acid oxidation. In order for these acetyl units to be utilized for fatty acid synthesis they must be present in the cytoplasm. The shift from fatty acid oxidation and glycolytic oxidation occurs when the need for energy diminishes. This results in reduced oxidation of acetyl-CoA in the TCA cycle and the oxidative phosphorylation pathway. Under these conditions the mitochondrial acetyl units can be stored as fat for future energy demands. \nAcetyl-CoA enters the cytoplasm in the form of citrate via the tricarboxylate transport system (see Figure). In the cytoplasm, citrate is converted to oxaloacetate and acetyl-CoA by the ATP driven ATP-citrate lyase reaction. This reaction is essentially the reverse of that catalyzed by the TCA enzyme citrate synthase except it requires the energy of ATP hydrolysis to drive it forward. The resultant oxaloacetate is converted to malate by malate dehydrogenase (MDH). \n\n\nPathway for the movement of acetyl-CoA units from within the mitochondrion to the cytoplasm for use in lipid and cholesterol biosynthesis. Note that the cytoplasmic malic enzyme catalyzed reaction generates NADPH which can be used for reductive biosynthetic reactions such as those of fatty acid and cholesterol synthesis.\n\nThe malate produced by this pathway can undergo oxidative decarboxylation by malic enzyme. The co-enzyme for this reaction is NADP+ generating NADPH. The advantage of this series of reactions for converting mitochondrial acetyl-CoA into cytoplasmic acetyl-CoA is that the NADPH produced by the malic enzyme reaction can be a major source of reducing co-factor for the fatty acid synthase activities.

It is a metabolic product which ultimately derives from glucose. You may have had some high sugar food stuffs. Then again there is the occasional error.

my guess is that glucose provides energy for the body tissues. if they provide energy, then the tissues are able to grow, develop, and function.

In the "second phase" of glycolysis are the reactions that will result in a net production of ATP for the overall glycolysis pathway:\n\n2 ATPs are consumed in Phase I (1 glucose à 2 glyceraldehyde 3-phosphate)\n4 ATPs are produced in Phase II (2 glyceraldehyde 3-phosphate à 2 pyruvate)\nNet production of ATP for glycolysis: (4 - 2) = 2 ATP molecules per glucose

thats a pretty loaded question there...the best I can summarize is:\nglycolysis:\nglucose + 2ATP + 2NAD+ +4ADP + 2Pi= 2 pyruvate + 2 ADP + 2 NADH + 2H+ + 2ATP + 2H20\nthis takes place in the cytoplasm of the cell\n\nKreb's/TCA/Citric Acid Cycle:\n3 NADH + FADH2 + 2CO2 for each turn of the cycle\nthis happens in the mitochondria\n\nETC:\nhappens in the mitochondrial matrix but is hard to explain without diagrams...basically you get +2.5ATP for each NADH that goes through and +1.5 ATP for each FADH2 that goes through

co2 is combined with water(h2o) and light to make glucose(c6h12o6), for food. This is a little simplified.

Glycolysis is a process that breaks down glucose without the presence of oxygen. This process occurs in the cytoplasm and involves 10 reactions that convert glucose to 3 carbon pyruvate. The first stage is priming of glucose. Glucose is converted to glucose 6 phosphate using a molecule of ATP, a process called phosphorylation. Then the glucose 6 phosphate is converted into fructose 6 phosphate through the process of isomerization. This is further phosphorylated to fructose 1, 6 bisphosphate (phosphorylation). This fructose 1, 6 bisphosphate is cleaved into two molecules of glyceraldehyde 3 phosphate. The two G3P undergo substrate level phosphorylation, a sequence of 5 reactions, involving dehydrogenation where NAD+ is reduced, dephosphorylation where two molecule of ATP is formed, isomerization where the phosphate group moves, dehydration where the molecule lose water and dephosphorylation where 2 molecules of ATP are generated and two molecule of pyruvate is formed. \n\nThe fact that glycolysis produces ATP fulfills a minor energy requirement of the cell, since ATP is the energy currency required for cellular functions to work. Another minor energy requirement is the formation of NADH, because the proton in NADH is required to activate the proton pump at the electron transport chain, which, in turn, activates the enzyme ATP synthase responsible for the synthesis of many ATP molecules (aerobic respiration = with oxygen)\n\nThe major relation of glycolysis to the energy requirements of the cell is the transformation of glucose to pyruvate. Pyruvate is decarboxylated and attached to coenzyme-A to form acetyl-coA, which then goes through krebs cycle. Both these processes form NADH (and ATP in the case of the krebs cycle), which can then provide many protons to activate ATP synthase. (aerobic respiration = with oxygen)\n\nMoreover, pyruvate can also be used in the absence of oxygen through anaerobic respiration. Through this process, ATP can be formed without oxygen and can thus fulfill energy requirements of the cell.\n\nVery long but hope this helps =)

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 living cells that utilize oxygen as part of cellular respiration. In aerobic organisms, the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production, the other two being glycolysis and oxidative phosphorylation.

The majority of fatty acids are metabolized using beta-oxidation. Essentially, a series of four enzymes oxidize the beta-carbon, shorting the fatty acid chain by two carbons. The electrons lost are transferred to electron carriers, and a molecule of acetyl-CoA is produced.\n\nOne round of beta-oxidation produces 1 QH2, 1 NADH, and 1 acetyl-CoA molecule. The citric acid cycle is used to convert the molecule of acetyl-CoA into 3 NADH, 1 QH2, and 1 GTP. Through oxidative phosphorylation:\n\n2 QH2 --> 4 ATP (2 per QH2)\n4 NADH --> 12 ATP (3 per NADH)\n1 GTP --> 1 ATP\n\nEach round of beta-oxidation shortens the fatty acid chain by two carbons and produces 17 ATP. Therefore, one molecule of palmitoleic acid, which contains 16 carbons, could undergo beta-oxidation 7 times and produce 131 molecules of ATP!\n\nPS The answer directly below mine is for one molecule of glucose... Not what you want. Lipids don't go through glycolysis. Acetyl-CoA also cannot enter gluconeogenesis in humans either because we lack the enzyme needed to enter the glyoxylate cycle.

Gluconeogenesis is the process of the body creating sugar (glucose) from sources other than carbohydrates or glycogen (percursor to glucose... stored in the liver).  Most commonly the sources are from proteins and fats/\n\nGlycogenesis is when the body converts stored glycogen into glucose.  Glycogen is easier for the body to store than glucose, but it has to be converted to glucose before it can be used by the body.\n\nGlycolysis is the breakdown of glucose.... usually to excrete it from the body.  LYSIS= destruction or breakdown.

Glucose is broken down into pyravate with a net gain of 2 ATP during glyclolysis, pryravate is broken down into CO2 and acetyl CoA.   acetyl CoA is oxidized in the kerbs cycle or citric acid cycle to for NADH, CO2, FADH2.  NADH passes electrons to the electron transport chain where the electron is passed along a chain of electron acceptors lossing energy each time.  The electron transport chain drives the H+ ions across the membrane of the mitochondria which ends up producing ATP.  Oxygen is the final electron acceptor.  I know thats a lot of info but its not close to all of it. I hope this helps
