Which is true about enzymes?
They increase the energy required for a chemical reaction to take place.
They increase the amount of reactant necessary for a chemical reaction to take place.
They decrease the amount of reactant necessary for a chemical reaction to take place.
They decrease the energy required for a chemical reaction to take place.



Answer :

Final answer:

Enzymes are catalysts that lower activation energy for chemical reactions without altering overall energy content; they are specific to substrates and vital for expediting biological processes.


Explanation:

Enzymes act as catalysts that lower the activation energy needed for chemical reactions to proceed. They do not change the overall energy content of the reactants and products but facilitate the reaction by lowering the energy barrier required to initiate it. Enzymes are specific to their substrates and play a crucial role in speeding up biological processes.
