Question

enzyme usually accelerates the reaction rate by about _____times
​

Answer 1

The speed of a reaction involves an enzyme increases as

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. Many enzymes change shape when substrates bind.

Answer 2

Explanation:

Enzymes help by putting the substrate(s) in the right position to react. Like all catalysts, enzymes increase the rate of chemical reactions by lowering the reaction's activation energy. Activation energy is the energy needed for the reaction to proceed.
