Answer 1

The activation energy needed for the chemical reaction decreased by an Enzyme.

Activation energy is the amount of energy required in a chemical reaction.

Enzymes lowers the activation energy by increasing the rate of reaction.

The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
