No, this is false.
Heating an enzyme can increase its reaction rate by providing more thermal energy, which helps molecules move faster and collide more frequently. This can result in more successful enzyme-substrate interactions and therefore increase the rate of the enzymatic reaction. However, excessive heat can also denature the enzyme and impair its function.
Enzymes do not heat up molecules to make them react. Instead, enzymes lower the activation energy required for a reaction to occur, thus speeding up the reaction by providing an alternative pathway. This allows reactions to happen at a biologically relevant temperature without the need for additional heat.
Cooling: When an enzyme is cooled, the activity is only slowed down. Heating: If an enzyme is overheated, it is known as a denatured enzyme. It changes shape to due the break down of it, and will no longer be able to bond with the substrate.
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
When hydrogen and oxygen molecules are burned in a closed chamber, they react to form water molecules (H2O) as a result of combustion. This reaction releases energy in the form of heat and light.

pH - denatures the enzyme by altering the charges on the enzyme. This will affect the structure of the enzyme and its ability to function. Heat - will denature the enzyme by breaking its bonds. This will stop the enzyme from being able to bond to a specific substrate molecule. Cold - not enough energy to reach minimum amount of activation energy needed to undergo reaction. The enzyme will not be able to react on the substrate.

Supersonic flights generate high temperatures, which can lead to chemical reactions in the air. The high-speed flow of air around the aircraft can cause molecules to break apart and react with other molecules in the atmosphere. This can create new compounds, such as nitrogen oxides, which can have environmental consequences.
Molecules react to thermal energy, or heat, as well as pressure. When you increase the temperature of molecules, they will increase their vibration and movement. Pressure can also allow molecules to move from one area to another.
The number of collisions with enough energy to react increases.

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.
Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.
Each enzyme has its ideal temperature
