Macromolecules and Enzymes

Enzymes are considered to be 

• Lipids

• Carbohydrate

• Protein

• Nucleic Acid

What is the purpose  of an enzyme?

• give permission for the reaction

• raise activation energy

• speed up reactions

• control how many reactions occur

Where do substrates bind on an enzyme?

• voltage-gated channels

• surface receptor

• calcium channels

• active site

What is structure A?

• Substrate

• Active site

• Enzyme

• Products

What is structure B?

• Substrate

• Active site

• Enzyme

• Products

What is structure D?

• Substrate

• Active site

• Enzyme

How do enzymes speed up chemical reaction?

• Increasing activation energy

• Decreasing activation energy

• Increasing deactivation energy

• Decreasing deactivation energy

What is a substance called if it speeds up a chemical reaction?

• reusable

• catalyst

• specific

• fragile

Each enzyme only has 1 substrate that will fit its active site.  What is this called?

• reusable

• catalyst

• specific

• fragile
