An enzyme catalyzes a reaction by?

Question

A) supplying the energy to speed up a reaction.

B) lowering the energy of activation of a reaction.

C) lowering the ΔG of a reaction.

D) changing the equilibrium of a spontaneous reaction.

E) increasing the amount of free energy of a reaction.

Answer 1

B because it speeds up the reaction so then activation energy becomes lower than it usually would

Answer 2

a catalyst lowers the activation energy of the reaction...  

B.

Answer 3

B)

Because it lowers the activation energy needed to break bonds between molecules to fasten up a reaction.

Hope this helps you!
