It usually lowers their effectiveness, i.e. slows the reaction rate.
Because fish spend their lives in cold water the enzymes in the flesh of fish are active at cold temperatures. Beef enzymes are inactive at cold temperatures. Another reason might be that fish have natural bacterial populations on their flesh while beef is cut from tissues free of bacteria.
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.
There are enzymes that speed up the chemical reaction components in food which leads to spoilage. Enzymes can be slowed down so that food spoilage doesn't occur as quickly by keeping food in cold temperatures.
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!
None, the canning temperatures denature and destroy any enzymes that were in the fruits.
the enzymes function at temperatures not above than 45 degrees Celsius and becomes denatured, therefore the enzymes will not work. At low temperature enzymes can work properly
The optimal temperature of enzymes in humans is about 37c, the same as the human body's temperature. However, some enzymes work at higher temperatures than 37 but not very high because higher temperatures denatures (destroy) the enzymes.
enzymes undergo denaturation when heated to high 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 ).

Enzymes can be denatured if the pH is too acidic or basic, or at very high or low temperatures.
cold temperature
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
