The amount of energy required to start a reaction is called the **activation energy**.

### Explanation:
Activation energy is a crucial concept in chemistry and physics, referring to the minimum amount of energy that reacting species must possess in order to undergo a specific reaction. This energy is necessary to overcome the energy barrier, enabling the reactants to transform into products.

In practical terms, activation energy can be thought of as the energy needed to break bonds in the reactants, allowing them to rearrange and form new bonds to create the products. It plays a significant role in determining the rate of a reaction; higher activation energy typically results in a slower reaction because fewer molecules have sufficient energy to overcome the barrier.

Thus, among the options provided, the correct answer is **activation**.
