In a polymerase chain reaction (PCR), the key components required include DNA templates, primers, nucleotides, and a DNA polymerase enzyme. However, one component that is NOT required for PCR to occur is a living cell, as the reaction can take place in vitro (outside of a living organism).
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
they reduce the activation energy required for the reaction to occur
they reduce the activation energy required for the reaction to occur
The energy required to start an enzymatic reaction is called the activation energy. It is the energy needed to initiate the chemical reaction that the enzyme facilitates. Enzymes lower the activation energy required for a reaction to occur, making it easier and faster for the reaction to take place.

DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.

Activation energy
The energy required to start an enzymatic reaction is called the activation energy. It is the energy needed to initiate the chemical reaction that the enzyme facilitates. Enzymes lower the activation energy required for a reaction to occur, making it easier and faster for the reaction to take place.
Catalysts increase the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. They are not consumed in the reaction, so a small amount of catalyst can be used multiple times. This leads to cost savings and efficiency in industrial processes.
Polymerase chain reaction
Oxygen is required for cellular respiration, because it is one of the ingredients needed for the metabolic reaction to occur, along with glucose.
A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
Activation Energy is the required energy needed in order for a chemical reaction to start.
