At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.
Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.

What is one way to speed up a chemical reaction besides adding enzymes?
Two ways: Add heat Add pressure
How can heat affect enzyme?
Heat would make most enzymes unnecessary as added heat would allow (many) reaction to achieve activation energy without the need of a helping enzyme. In a biological system most enzymes are proteins and as heat denatures proteins the effect would be to destroy their functionality.
During photosynthesis what chemical reaction gives off heat?
Exothermic Reaction.
Why are enzymes necessary for anabolic reaction to occur in living organisms?
Enzymes allow many chemical reactions to occur. They catalyze reactions by lowering the activation energy, which is the amount of energy needed to trigger a chemical reaction. Whereas heat can provide energy to trigger reactions, temperatures needed to reach activation energy for most metabolic reactions are often too high to allow cells to survive, so enzymes are in fact needed if metabolism (anabolic or catabolic) is to occur.
Which will speed up a chemical reaction A Apply heat B Increase the concentration of the reactants C Grind up the substance so there is more surface area?
The 2 ways to increase chemical reaction rate are applying heat or a catalyst. So it is A : Applying heat. ;)
How does heat and cold can affect a chemical reaction?
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What is one way to speed up a chemical reaction besides adding enzymes?
Two ways: Add heat Add pressure
Does adding heat energy affect the rate of reaction in a chemical change?
it depends on what chemicals used
What can change the rate of reaction of enzymes?
Heat can change the rate of reaction
What is a heat reaction?
This the heat released during a chemical reaction.
What chemical reaction happens to salt when you heat it?
when we heat the salt there chemical reaction is takes place
When heat is increased does the chemical reaction speed up?
The effect of heat on a chemical reaction will depend on whether the chemical reaction is exothermic (producing heat), or endothermic (requiring an input of heat). If the reaction is endothermic, then adding heat will increase the speed, but the opposite is true for an exothermic reaction.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
How are enzymes and activation energy related?
The activation energy, once put in force, will be affected by the density, static, and kinectic energy of an object, but will still have a direct impact on the energy of reaction that is yielded from the initial force.
What helps speed a chemical reaction?
A catalyst is a substance that speeds up a chemical process without actually changing the products of reaction.
Can a chemical reaction cause heat?
Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change
