How do cold temperatures affect enzymes?
the low temperature makes the enzyme become temporaritly inactive, this means that it is so cold for the enzyme that it simply doesen't do anything. hope this helps!
What happens to an enzyme when its put into a hotter or cooler place?
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.
What types of conditions affect enzymes?
if the envirionment is cold, the reaction rate decreases. if the envirionment is warm, the reaction rate increases. however, if the envirinment is too hot, the enzyme will be denatured. a pH out of the enzyme's optimal range will also denature it. when an enzyme is denatured, it looses its shape a its active site is no longer able to recive the molecule and break it down.
What is the name for treating tissue with cold temperature?
Cryotherapy - The treatment of tissue with the use of cold temperatures
Why don't enzymes work as well at lower temperatures?
he cold is not as intuitive as heat. Heat is the abundance in a system and cold is the absence of energy in a system. Hence athermometer is the an instrument that measures the average kinetic energy of its surroundings. Why do enzymes not work as well in the cold it is because the energy of the system is decreasing causing the molecules to "slow down" there by slowing the diffusion in a system. The enzymes normal substrate is not diffusing a quickly as it would in a heated system, raising the enzymes Km ( affinity for its substrate ).

In cell isolation why must cold buffer and centrifugation be carried in cold temperatures?
TO STOP ENZYME ACTIVITY
What does the refrigeation of food do with the way enzyme work?
Too cold for enzyme activity.

Will enzyme activity increase with an increase in temperature?
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.
Does cold temperatures affect the strength of a magnet?
It dose effect because the properties get unbalanced.
How does low temperatures affect enzymes?
cold temperatures cause enzymes to inactivate, meaning they are no longer useful. at height temperatures enzymes denature, meaning they are also no longer useful. The difference is that at low temperature, when an enzyme inactivates it can always be heated, and used again. Yet after an enzyme is denatured by heat it is destroyed, this is because the heat causes the enzymes to lose its shape, making it imposible for the substrate to react with the enzyme.
Do cold temperatures have a vasoconstricting effect on blood vessels?
Yes. Increased body temperature that is associated with a cold can cause the vasodilation effect and heart rate increases
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.
Why are tissue ice cold when homogenising them?
Ice cold water is used, to control the experiment to ensure that the enzyme activity is kept constant, therefore the enzymes are unable to affect the homogenisation.
What environmental conditions must exist for an enzyme to function properly?
Warm and cold temperatures are always nice and accurate for that type of weather! So sexy!

Why flies hate the cold?
A fly's activity level is seriously affected by cold weather. It becomes much less active and if the cold temperatures continue, the fly will eventually die.
