why the glucose and cyanide act against each other?

Glucose is important to the body because it is broken down into just water and carbon dioxide in the process of oxidative phosphorylation in the mitochondria of your cells-this requires oxygen..  This is where your body gets 95% of it's evergy-for example, runners use oxydative phosphorylation (aerobic energy) and can go steadily for 26 miles (or more)-while weightlifters when lifting use primarily anaerobic energy (without oxygen)-that only can give energy for a minute or so.  WIthout aerobic metabolism you would die in a few minutes.  So, glucose plus oxygen is where you get energy, and it happens in the mitochondria of cells.  Cyanide interfers with this reaction in the mitochondria, so that oxygen cannot be used to make energy (so cyanide primarily works against oxygen, but since it's glucose + oxygen that is burned to make the energy, is might as well work against glucose as well).  Burning glucose for energy using oxygen is exactly the same as burning fuel in a fire.  If you start a fire, but keep it from getting oxygen, it'll go out- cyanide starves your body of the oxygen, so *your* fire goes out.

I think it has something to do with lowering the boiling point of the sugar.

If a person puts a very small amount (less than 250 mg) of a cyanide(potassium cyanide,for example) on his tongue,it would be more than sufficient to kill him in less than 5 seconds.

HCl interacts with pentoses producing furfural or furan-2-carboxaldehyde. The reaction causes a bright pink color. This distinguishes pentoses (sugars containing five carbons) and hexoses (sugars containing six carbons).

all of those?\nalthough glucose ususally goes trough with active transfer

In addition to what Jen said, I would also like to point out that although isoenzymes by definition catalyze the same reaction, they often do it with different kinetic parameters.\n\nFor example, there may be different reaction order, affinities (K-constants), and the like, between two isozenzymes, even though they both perform the same product-to-substrate conversion.

It depends.  \n\nTable salt, NaCl, theoretically doesn't effect the pH, strong electrolytes are weak acids and bases, however in practice I believe that it slighty basic.  However salts can be either Basic, like soduim cyanide, NaCN, or acidic, like ammonium cloride, NH4Cl.\n\nSugar does effect the pH because of the acidic proton on the alcohol portion of the sugar.  This does not mean that a sugar is acidic, but it means that if sugar is put with a strong base the pH will go down because some of the base will react with the sugar.

the C6H12O6 represents a molecule of glucose that a cell is metabolizing. Cellular respiration oxidizes (burns) food molecules into carbon dioxide and water.  So, the C's in glucose are eventually converted into carbon dioxide (the 6 CO2).  The O2 is oxygen that a cell gets from its environment.  If you're thinking of this happening in you, the oxygen is absorbed by the bloodstream in your lungs from the air that you breathe. The O2 is used to form the water.

oxidation, i think.\n\nin this case, simple sugar reacting with oxygen in the air.\n\nIt's been a long time since my Chemistry 101 days.  Hope I got it right.

Fructose and glucose are different in many ways.  The chemical formula only shows the elemental composition.   Even glucose has 8 different steric isomers.  \n\nGlucose is an aldohexose and fructose is a ketohexose.  In the early days, glucose was called dextrose because it rotated plane polarized light to the right and fructose was called levulose because it rotated plane polarized light to the left.\n\nFructose is significantly sweeter tasting than glucose and less quantity is required to reach the same sweetness level.\n\nFructose and glucose are metabolized differently.  Fructose enters more directly into glycolysis as fructos-6-phosphate and has little effect on insulin levels.\n\nOddly both fructose and glucose will give the same product when reacted with an excess of phenylhydrazine.

"Normal" bonding occurs when a ligand donates electrons to a metal. When a metal ion donates electrons back to the ligand, this is called back-bonding. The combination of normal bonding and back-bonding creates a strong bond between the ligand and the metal. The reason that phosphines, carbon monoxide, and cyanide are so poisonous is because they bond readily to iron in biological systems and cannot be displaced by the ligands (such as oxygen) which should bond to iron in normal metabolic processes.

This time we use oxygen to burn the sugar:\n\nSugar + Oxygen = Carbon Dioxide + Water + Energy\n\nUsing glucose:\nC_6H_12O_6 + 6 O_2 -> 6 CO_2 + 6H_2O + Energy

The quickest absorption will be of the 2-glucose "polymer."  That way, every cut by the enzyme yields two glucoses.  With any other chain length, each cut would yield one glucose until the last cut, which would yield 2.\n\nAnything wrong with amalyse?

One bit to add.  The only exception to this is the polyatomic ion, ammonium. (NH4+) It acts like the cation.
