It becomes denatured which means it changes its shape. Enzymes that change their shape do not function properly anymore.

What is the effect of cold temperatures on enzyme activity?
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
What is denaturing enzyme?
enzymes are proteins. when you denature a enzyme you destroy the protein structure/shape. it happens a couple of ways; 1) temperature (they have a 'optimum temperature') at certain temperatures enzymes are denatured 2) Ph, again, they have a 'optimum pH at which they work best, and certain pH levels where they are denatured. 3) Various chemicals..
Why do enzyme molecules change shape at high temperatures?
The rate of enzyme reactions is affected by temperature. All enzymes have an optimum temperature range in which they work most efficiently. An enzyme is most active at its optimum temperature. A temperature rise beyond this point reduces enzyme activity till it completely stops. This happens because the enzymes structure has changed, (often a loss of the correct folding of the molecule) and it's irreversiable. The change of the structe makes the enzyme become useless because it can't bind to subrates to make chemical reactions.
Enzyme that adds nucleotides to exposed nitrogen bases?
The enzyme that adds nuclleotides to exposed nitrogen bases is DNA polymerase. This is how DNA can be replicated or repeated in the cell cycle.
What is it called when extreme conditions like high temperatures and extreme pH values change the shape of an enzyme?
Proteins become "denatured", meaning they change shape., break down and can't function the way it is supposed to, and could potentially cause a problem by getting in the way of other proteins.
Why do enzymes lose their function when they are subject to extreme temperature changes?
When an enzyme is exposed to high temperatures, the enzyme will denature or unfold. Therefore, the enzyme will not function properly.

What is one kind of extremozyme?
An enzyme that works under extreme conditions like high temperatures.
If an enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
It is reduced
In a enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
catalyzed reaction
What 2 things will change the shape of an enzyme and therefore stop an enzyme from working?
1. Some solvents 2. Temperature changes (when exposed to high temperatures, the protein will denature, rendering it inactive)

What happens to enzyme actvitys when temperature rises?
The enzymes will stop working because they only work in certain temperatures.
What does 'enzyme inactivation' mean?
Enzyme inactivation refers to a certain period when the enzyme is unable to catalyse a particular reaction. For example some enzymes are inactivated at extreme temperatures of cold or heat. At this particular time the enzyme does not perform its function of catalysis but after favourable conditions return the enzyme wil resume its catalylitic function.

What is the Optimum temperature for enzymes?
It depends on the type of enzyme and where that enzyme is located. For example, an average enzyme in the human body prefers 98.6 degrees F plus or minus a few degrees depending on where the enzyme is in the body. It is interesting to note that a high fever is fatal to the human body because the temperature of the body gets too high and the enzyme begins to unravel. Therefore their function stops and, without that function, the human body will begin to shut down leading to possible death. Other enzymes function in completely different temperatures. For example, extremophiles are organisms that live in extreme conditions (hence the name) ranging from about 0 degrees Fahrenheit to upwards of about 180 degrees F. Obviously they need their enzymes to function at these temperatures extreme temperatures and therefore these temperatures are their optimum temperature.
