Respuesta :

They lower the activation energy, that is required for a specific process.

The enzyme works like a lock and key, where the lock is the enzyme that gets activated by a molecule the "key". Once they bind to each other the process gets started.

Without enzymes the process would have to occur entirely on it's own.

Answer

By lowering energy of activation of the reaction.


Explanation

High energy produced during the metabolism of reactant to product. Due to the large free energy of activation, the speeds of uncatalyzed biochemical reactions are often exceedingly slow. Enzymes lower this energy of activation so that more molecules have adequate energy to carry into the transition state to speed up the rate of reaction.
