lowering the activation energy makes the reaction take place much _?

faster

every enzyme has an optimum _ and _ at which it functions best

pH, tempurature

without enzymes, the chemical reactions would be to _

slow

the _ of the enzyme is so specific that only the substrate can fit into the active site

shape

do enzymes cause reactions to take place?

no

the elements or compounds that enter into a chemical reaction

molecules

this is the energy that is required in the reactant molecules in order to start a reaction

activation energy

a pocket or groove on the surface of the enzyme in which substrate molecules must fit

active site
