Question

activation energy is best defined as the energy that is transferred to the products at the end of the reaction. is released when an enzyme binds its specific reactant molecules. is used to make new chemical bonds and form products. is required for a chemical reaction to proceed. is required to form products that are at a higher energy than the reactants.

Explanation:

Activation energy is the minimum energy that reacting species must possess to undergo a specified chemical reaction. It is the energy hurdle that must be overcome for a reaction to start.

Answer:

is required for a chemical reaction to proceed.
