It is converted into ATP (adenine triphosphate).

how would they be uncoupled? \n\nUnless you are trying to say that one of them isn't functioning. Perhaps ATPase is inhibited or something.\n \nif so, then the most immediate would be a build up of the proton concentration in the mitochondrial intermembrane space. Physiological impact of that... i'm not too sure.\ni suppose NAD and FAD will be recycled initially cos ETC is still functioning, but obviously ADP is not being phosphorylated to form ATP. Deficiency of ATP = detrimental effects.\n\nif the ETC is disrupted (cytochrome inhibition by cyanide?), perhaps anaerobic respiration will kick in for a while? considering tt the aerobic route is faulty, there will be an increased dependency on glycolysis and the pyruvate/lactate route. but a net gain of 2 molecules of ATP per glucose molecule isn't very beneficial.

Cyanide binds better to cytochrome 3a than oxygen and this affects the electron transport chain.  The last step in the electron transport chain is the transfer of electrons to oxygen gas using the cytochrome protein.  Cyanide binding to the cytochrome locks the protein and prevents electron transfer out of cytochrome 3a.  This messes up the whole electron transport chain as everything gets backed up in the mitochondrial inner membrane, which is where the cytochrome and other electron transport proteins are located.  \n\nSo when the electron transport chain is backed up this prevents the reducing power created in glycolysis and the Krebs Cycle from being used.  The reducing power from those two processes is what is used to create most of the energy derived from respiration.  So without use of the electron transport chain, which does not work when cyanide is present, only 3 or 4 ATP are made per glucose in the respiration reactions.  With the electron transport chain, in the absence of cyanide, about 34 ATP total are made from the respiration reactions.  \n\nSo overall cyanide greatly reduces the efficiency of respiration by preventing the use of a critical respiration protein.  The presence of cyanide in a cell can cause cell death within minutes due to the extreme inefficiency at which the cell produces energy.

Step 1 - ATP is invested by adding a P to glucose\n          Step 2 - Glucose-6-P is convertedinto Fructose-6-P\nStep 3 - A second ATP is invested \nStep 4 - The 6 carbon molecule issplit into two three carbon molecules.\nStep 4.5 - Dihydroxyacetone -P is converted into 3-P-glyceraldehyde\nStep 6 - every subsequent step occurs 2xNADH is produced as another P is added\nStep 7 - (2) ATP is recovered\nStep 8 - The P is moved from the 3-carbon to the 2-carbon\nStep 9 - A structural change is made\nStep 10 - (2) ATP is recovered\nStep 11 - NADH is produced anda CO2 is produced\n2 pyruvate are made from the process

Intersting question but there's not enough info to make an informed decistion...  First, just adding sugar to water isn't going to change the strength of a given h-bond. It wil allow water to make new bonds with the oxygen in the sugar, but the strength of a water-water h-bond will remain the same. Second, there are several different environments with which one could be concerend, the interfacial region, where the sucrose is most likely to affect the molecular ordering of water, has even more modes of h-bonding that might be affected but again the overall energy of the existing bonds would not change, but new modes comprised of the sucrose-water moieties would likely be observed. \n\ngive me a little more background and i can give you more information.

From respiration: Here, glucose molecules in the cell are broken down; the molecules have strong bond between them and so when they are broken, energy is provided(by mitochondria) and when new molecules are formed, energy is released, which the cell uses for various processes.\n\nFrom protein synthesis: It occurs on the ribosomes in the cytoplasm, and aminoacids are combined to form proteins and this releases energy.\n\nFrom ATP(adenosine tri-phosphate): The ATP molecule is a packet of energy which stores the energy released during any process going on in the cell and then releases the energy as and when required by the cell.

Sugar doesn't melt.  Rather, it decomposes.  It decomposes into its constituent elements, which are C, H, and O.  The H and O are given off as gases, leaving the C, carbon, left behind as a black mass in the bottom of the test tube. It's only carbon, presuming you heat it enough to drive off all of the sugar molecules.

The pathway of glycolysis can be seen as consisting of 2 separate phases. The first is the chemical priming phase requiring energy in the form of ATP, and the second is considered the energy-yielding phase. In the first phase, 2 equivalents of ATP are used to convert glucose to fructose 1,6-bisphosphate (F1,6BP). In the second phase F1,6BP is degraded to pyruvate, with the production of 4 equivalents of ATP and 2 equivalents of NADH.

Glycolysis is the breakdown of glucose into 2 molecules of pyruvate.  It occurs in the cytosol of the cell.  There are 10 enzyme-catalyzed steps, in which 2 net molecules of ATP are produced.

The significance of the TCA cycle is that it takes the left-over carbon from glycolysis and breaks it down in such a way as to yield a large amount of useable energy.\n\nThe energy is first transferred to NAD+ through a highly charged hydrogen atom, and the result is shown as NADH + H+. This molecule carries the energy to the respiratory chain system, where three ATP molecules are energized from each one.

when we take in the food during the process of respiration the glucose is broken down to pyruvic acid CH3COC0OH BY THE process of glycolysis , initially by taking oxygen by cytoplasm . when it gets more oxygen the pyruvic acid enters mitochondria and is converted to CO2 AND H20 . This cycle is called KREB's cyle . the synthesis of ATP molecule takes place in the F1 particle of mitochondria . \nthe equaton is \nC6H12O6+O2---->CH3C0COOH + O2--->CO2 + H20 \nthis process is called aerobic trespiration \nrespiration involves oxidation of food ....\nthus kreb cycle is aerobic respiration and increase in oxygen increases it !!!!!\nPLEASE VOTE IT AS THE BEST ANSWER IF YOU LIKE IT ..PLEASE......\nI THINK I HAVE ANSWERED YOUR MANY QUERIES

It is called glycolysis.  Also note that one 6-carbon glucose is broken down into two 3-carbon compounds.  Each 3-carbon compound is called pyruvate.

You're forgetting something with your reasoning here.  It is true that in chemistry, creating bonds releases energy, but how do you get particles to create bonds between?  You have to break other bonds, which requires energy.  If catabolic pathways release energy when they break down complex molecules, the amount of energy it takes to break those bonds is less than the amount of energy released when new bonds are formed from the broken-up parts.

Cells produce energy via cellular respiration. Glucose is broken down in the cytoplasm into pyruvic acid and then further broken down in the mitochondria. Free radicals, mainly methyl, work by bonding to your DNA and effectively turning off genes. If the right (or wrong) combinations of genes are turned off via free radicals, cancer could be the result.

"My Beautiful..." is correct.\nWhen you dissolve sucrose in water, it first just makes a sucrose solution, but in time, the sucrose will slowly break down into glucose and fructose in solution.
