Enzymes provide a site where reactants called substrates can be brought together in an enzyme-catalyzed reaction. The site is called the

• enzyme substrate complex.
• reaction site.
• active site.
• lock and key.

An enzyme speeds up a reaction by

• lowering the activation energy.
• raising the activation energy.
• releasing energy.
• absorbing energy.
