Activation energy Group of answer choices is only required in catabolic reactions that release energy. is not required at all when reactants are in the presence of an enzyme. always gets absorbed and increases the potential energy of the final products. Two of the answers are correct. is used to break reactant bonds and/or make new product bonds.

is used to break reactant bonds and/or make new product bonds.

Explanation:

The correct answer would be that activation energy is used to break reactant bonds and/or make new product bonds.

The activation energy is the minimum energy that must be overcome by the reactants in a reaction in other to become products. In order for products to be formed, the bonds between reactants must be broken and new ones must be formed to arrive at the products. In other words, the activation energy can be seen as the energy required to break the bonds between reactants and form the bonds between products during the course of a reaction.

Activation energy is required even in the presence of enzymes. The latter only catalyzes reactions by lowering the minimum energy required to break the bonds between reactants and form new ones between products.
