Question

Enzymes increase the rate of reactions. Pick the right answer:

1. The enzymes increase the rate of the reaction due to the changes they themselves undergo.
2. Enzymes repeat their action again and again to accelerate activity.
3. Enzymes increase the activation energy of the reaction.
4. Enzymes alter the activity profile of the substrate.
(I hope it makes sense. I had to translate it from my native language. Help is much appreciated!).
