How does an enzyme influence a chemical reaction A. It provides the substrate needed for the reaction to occur
B. It raises the activation energy so that a reaction can occur
C. It speeds up the reaction rate
D. It is used as a reactant to form the product

It speeds up the reaction rate

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.

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.
