• Decreased Kinetic Motion
• Increased H-Bonding
• Dissociation of Ionic Compounds

Most enzymes have the ending:

• -ase
• -ose
• -ic acid
• -ate

The molecule an enzyme is working on is called the:

• Substrate
• Solvent
• Allosteric Inhibitor
• CoEnzyme

When a molecule can occupy the same active site as the substrate, a situation called __________________ can result

• Competitive lnhibition
