Question

How does an enzyme influence a chemical reaction?

Choose 1 answer:
It provides the substrate needed for the reaction to occur.
It speeds up the reaction rate.
It is used as a reactant to form the product.
It raises the activation energy so that a reaction can occur.

Answer 1

It speeds up the reraction rate.

Step-by-step explanation:

Enzymes lower the activation energy of a reaction by binding to substrate and holding them in a way that allows the reaction rate to increase.

Answer 2

It speeds up the reaction rate

Step-by-step explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
