yeah above 45degree C, it starts to denature
They are important because they can be set to a specific temperature which. You can place test tubes filled with things to see if the temperature affects how they work. For example, say you wanted to see if an enzyme worked at a certain temperature like 100 degrees F. You would put it in the water bath with it mixed with the substrate it works on, if the temperature was too high you would see the enzyme would denature.
Because enzymes have a specific shape to interact with the molecules they are designed for, increasing temperature 'stretches' them. That's why its serious if someone has a fever over 40ºC, it can inactivate enzymes in the body, this can harm the individual. and under 37 is called hypothermia which is also serious
It is now well established that proteins (enzymes) denature at both high and low temperatures. Denaturation, by heat or cold refers to the loss of the 3-dimensional structure of the enzyme, which otherwise it possesses under physiological conditions.When a enzyme experiences this structural instability, it leads to a loss of its functionality, since the 3D structure of a enzyme can be directly co-related with its function.
Simply put, enzymes are proteins and proteins can denature (break) under the right conditions. These conditions would include temperature and pH (however these are not the only factors) and so the changing of pH could definitely affect hexolkinase (or did you mean hexokinase? which would make more sense).
If an enzyme is put under certain conditions, including proximity to heavy metals, pH extremes, and temperature extremes, the enzyme will break apart. This means that the enzyme has been denatured, and will no longer work. It depends on how much the enzyme's shape has changed. This is dependent on what enzyme is in question and what conditions it was put under.
It is increasing in temperature. When you put a pot of water over a lit stove, it evaporates into its gas form, water vapor, which can also be called steam.
The higher a temperature is, the faster things go. This is because molecules move faster at higher temperatures. The opposite is true for cold temperatures- molecules move slower, and so do the reactions. Temperature also has different effects on specific organisms-- for example, a hot spring bacterium has enzymes that generally work better in hotter temperatures.
gas can be converted to liquid by increasing pressure and by lowering temperature of gas
Simply put, heat will denature DNA. Technically speaking, DNA has something known as the the melting temperature (which is the temperature at which a strand of DNA is separated halfway). And melting temperature is itself dependent on several other factors (like G to C ratio, salt conent, and pH).

The rustin of iron can be treated as any other chemical reaction. Increasing temperature increases the rate of reaction. Hence increasing temperature can increase the rate at which iron rusts.
Most likely an enzyme from one of your body cells would NOT be able to function in a place as hot as a hot spring because the enzyme would get denatured. denaturization can occur when enzymes are put to extreme temperatures. Since the enzyme is used to your body temp. it is a huge increase to put the enzyme in almost boiling water.
