Do enzymes increase the activation energy of biochemical reactions?

Answer 1

Enzymes speed up a chemical reaction by lowering the energy required for a reaction to procede, the Activation Energy (Ea). The overall change in energy of the reaction is unchanged, so the net amount of energy released in a reaction is not increased.

Answer 2

Functionally, enzymes do not increase the amount of energy.

Enzymes bind non-covalently with specific molecules called substrates and decrease the free energy required for the substrate to transform into the product.

The free energy change of an enzyme catalyzed reaction is lesser than that if the reaction were to proceed by other means

Answer 3

Enzymes may decrease the amount of energy released in a reaction. This happens when the temperature increases a few degrees above body temperature when most enzymes start to denature.

Answer 4

It depends on the specific function of the enzyme. If the enzyme is able to act as a catalyst, then yes, it will increase the rate of the reaction.

Answer 5

no. they act as a catalyst to reduce the activation energy so the reaction can take place at a lower temperature.

Answer 6

yes
