The area that the substrate fits into on the enzyme is called the:

• Active Site
• Allosteric Site
• DiSulphide Bridge
• β-Pleated Sheet

NGSS.MS-LS3-1

Enzymes catalyze reactions by ___________ Activation Energy.

• Increasing
• Decreasing

Tags

NGSS.HS-PS1-4

Enzymes speed up reaction rates by changing:

• Activation Energy
• pH
• Hydrogen Bonds
• Kinetic Energy

NGSS.MS-PS1-2

NGSS.MS-PS1-5

At high temperatures enzyme activity declines because of:

• Denaturation
• 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

This type of reaction is a:

• Dehydration Synthesis
• Neutralization
• RedOx Reaction
• Phosphorylation

Which explanation best fits the graph for pH's effect on an enzyme?

• As the pH gets closer to neutral more H-Bonds are broken
• Larger numbers of H+ & OH- ions distort the active site
• There are more collisions between substrates and active sites near the optimal pH
• Low pHs cause more H-Bonds to happen near the active site

What enzyme is likely to catalyze this reaction?

• Kinase
• OxidoReductase
• Isomerase
• Transferase
