In the human body, enzymes function as catalysts to speed up reactions by helping to lower the activation energy needed to start a reaction.
Although some RNA molecules can also act as enzymes, proteins constitute the vast majority of enzymes.
The primary function of enzymes is to decrease the activation energy, or the energy required for a process to start. Enzymes bind to reactant molecules and hold them in place to enable the chemical bond-forming and bond-breaking processes.
The energy of the transition state, which products must pass through in order to become reactants, is reduced by enzymes.
Instead of using energy to move till they collide at random, they might group the reactants together to make it easier for them to interact. They could direct the process along a different pathway with lower activation energy.
By tying them to the active site, they might place the reactants correctly. As a result, the reactants can interact with less energy because they won't have to fight against intermolecular forces that would normally try to separate them.
Temperature, ionic circumstances, and environmental pH all have an impact on how quickly an enzyme.

Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
