Question

Enzymes _______ the activation energy threshold required to start a chemical reaction.

raise
lower

Answer 1

lower

Step-by-step explanation:

Enyzmes usually lower the activation energy required to start a chemical reacion. It's useful to remember enyzmes as compounds which help speeden up different chemical processes. They do this by decreasing the required activation energy and therefore increase the chance of a chemical reaction occuring.

Answer 2

Enzymes lower the activation energy threshold required to start a chemical reaction.

Definition of Enzymes: a substance produced by a living organism which

acts as a catalyst to bring about a specific biochemical reaction.

Hope that helps!
